The overall philosophy at every BMW CCA Club Racing event will be to offer "a competitive driving experience for all BMW CCA enthusiasts, in all types of factory authorized or constructed BMW's in a fun, safe, and friendly environment where the primary emphasis is on clean driving and machinery preservation." This philosophy will be maintained by the application of common rules and procedures and the BMW CCA Club Racing Stewards at each event.

These rules are intended to be simple, easy to read and brief. It has never been the intent of the administrators of BMW CCA Club Racing to write an epistle similar to the General Competition Rules of the SCCA. It is our wish that competitors follow the charter of BMW CCA Club Racing and adhere to the spirit of competition that has developed.

The STOCK class is intended for those cars typically seen at drivers schools owned by an enthusiast who has done simple modifications to improve the basic performance of a stock, street driven BMW. As outlined in the rules, suspensions may be modified by adding performance components. The engine may only be modified in that chips for the fuel injection system may be changed. All other modifications to the vehicle are intended for safety purposes only.

The PREPARED class is intended to invite vehicles prepared for SCCA Improved Touring competition into BMW CCA Club Racing. In order to accommodate those enthusiasts with modified, street driven vehicles, some compromises beyond the SCCA regulations have been incorporated into these rules. The intent of this class is to allow the more progressive enthusiast and the experienced racer to participate in BMW CCA Club Racing with a higher level of preparation that is still street licensable, street drivable and in keeping with the spirit of the “original” vehicle.

MODIFIED AND SUPER MODIFIED - Those wishing to build dedicated-purpose racecars have two classes to compete in. Vehicles in the Modified classes have the option of full race suspensions, unlimited modifications to the BMW engine and BMW transmission. Super Modified is intended for cars whose preparation level exceeds those allowed in Modified plus designated purpose-built, BMW-powered racecars that meet the eligibility criteria.

General Rules

1. Philosophy - The BMW CCA Club Racing Program is designed to be fun, safe and competitive. Good sportsmanship, honesty, and a sense of fair play should exist at all BMW CCA Club Racing events.

2. 13/13 RULE - The "13/13 rule" of vintage racing will be in effect at all BMW CCA Club Racing program events. Conduct which jeopardizes safety or results in dangerous or damaging situations will not be tolerated. Under this rule, any single or multi-car incident which results in car damage will, at the discretion of the Competition Steward, cause the following:

A. The BMW CCA Club Racing Competition and Technical Stewards will collect and review all information relating to the incident, including corner worker and other observer reports, driver statements, and damage reports in order to make a determination of fault and assess penalties.

B. A driver who is found to be at fault will be:

1. Excluded from competition for the remainder of the event at which the incident occurs. For a multi-day event, the Steward's determination may be for the entire event or the balance of the race day in which the incident occurs.

2. Placed on probation for a thirteen (13) month period. If during this probation period the driver is involved in another contact incident, competition privileges will be suspended for thirteen (13) months.

3. For SINGLE CAR incidents the event Competition Steward is authorized at his discretion to access penalties of 3, 6, or 13 months probation. If the driver is on probation from a previous incident, then a 13-month suspension will be assessed.

4. Subject to suspension from the next BMW CCA Club Racing event in which they could have competed.

5. Excluded from the event results or listed as "DQ".

6. Excluded from any event points or awards that may otherwise be available

7. For the event, any racer currently on probation MUST attend any/all scheduled "Rookie" meetings at the next race they participate in.

C. In addition, a penalty may be assessed by the event Competition Steward for any infraction of the rules, incident, or personal conduct that is not is keeping with the spirit and intent of BMW CCA Club Racing.

The following are examples of actions that could warrant penalty:

1. passing under yellow or red flag

2. blocking

3. technical rules infraction

4. unsportsmanlike conduct (both on and off track)

5. reckless and dangerous driving

The addition of penalties for passing under yellow (or red) flags, blocking, technical rules infractions, unsportsmanlike conduct, and reckless and dangerous driving is intended to emphasize the focus on SAFETY and good sportsmanship that are the tenets of BMW CCA Club Racing. Assessment of penalties for these incidents will be based on evaluation by the event Stewards of the competitor's attitude and behavior. For example, blocking may initially incur a furled or waved black flag warning.

Repeated violation and/or additional incidents will, at the discretion of the event Competition Steward, result in a penalty up to and including probation or suspension.

Any driver involved in an on track incident causing visible damage to their or another driver's car must report to the event Technical Steward with the car (if drivable) within 30 minutes of the checker flag of the session in which damage incurred. Failure to do so will subject the driver to penalty.

All incidents shall be resolved as soon as practical after the incident is reported/observed with the objective being resolution and assessment of penalty at the event.

Drivers penalized will be notified in writing of the penalty assessed. Drivers are required to present notice of such penalty to race Competition Stewards at any races they participate in while the penalty is in effect.

Drivers are responsible for their guests and crew. Inappropriate actions by guests or crew can result in a 13/13 penalty for the driver.

3. Driver Eligibility - Only BMW CCA Club Racing Program “licensed” drivers are eligible to compete.

4. Unlisted Modifications - Any modification not specifically listed is not allowed. In other words, if the rules don’t say you can do it - DON’T.

5. Stock classes are based on factory published horsepower, torque, weight and gearing. All cars must conform to these figures if tested. The BMW CCA Club Racing Stewards reserve the right to test any car for conformance.

6. Eligible Vehicles

A. Open-wheel cars are eligible in historic and demonstration classes only.

B. BMW manufactured automobiles, using BMW manufactured chassis, engine case and transmission case. Engine and transmission must have been factory designated for automotive application.

C. Factory-approved racecars are eligible. (Documentation of factory approval is the responsibility of the car owner).

D. Purpose-built, BMW-powered racecars specifically approved by BMW Club Racing.

7. CAR NUMBERS, CLASS IDENTIFICATION, DECALS:

A. All cars must display easily readable numbers and class designation for identification. These must be displayed on each side and front (hood) of the vehicle, of significant size and color differentiation from the body color so as to be clearly seen by timing and scoring officials. Numbers shall be a minimum of 8 inches high with a 1-1/2 to 2 inch stroke. Class identification shall be near the numbers and be a minimum of three inches high. Class identification will consist of 2 letters, i.e. A-Modified = AM, I-Prepared = IP, J-Stock = JS. Identification for a car in Super Modified will be the letters SM.

B. Competitors may request assigned numbers from the National Registrar. The goal will be to allow racers to use requested numbers. Where duplications exist, deference will be given to the racer with the lowest Club Racing license number (as long as he/she is a paid registrant at least two weeks before an event date). Race officials reserve the right to assign car numbers for specific events.

C. Club Racing officials may require series and sponsor identification (decals) in specific size, contrast and placement to be displayed on cars before being allowed to race.

8. Steward’s Decisions - Any decisions of the BMW CCA Club Racing Stewards concerning safety, eligibility, acceptance, etc., are binding. Vehicles entered in the program must, in addition to meeting safety and classification rules and regulations, be presented in an attractive and eye pleasing manner. BMW CCA Club Racing Stewards reserve the right to refuse to accept any vehicle which they feel does not “conform to the spirit” of the BMW CCA Club Racing Program.

9. Reclassification - BMW CCA Club Racing National officials reserve the right to reclassify a car and driver based upon a review of previous performance.

10. Award Eligibility - Vehicles must compete in the class to which they are classified to be eligible for awards.

11. Tow Hooks - It is recommended that all racecars be equipped with front and rear tow hooks.

NOTE:

No express or implied warranty of safety or fitness for a particular purpose shall result from publication of, or compliance with, these rules and/or regulations which are intended as a guide for the sport and are in no way a guarantee against injury or death to participants, spectators or others.

Safety

These safety regulations are adapted from various racing organizations. If you are in doubt as to an interpretation, ask, or follow SCCA specs for an IT, production or GT class car. If you are going to err, do so on the side of being too safe!

1. TECH INSPECTION

A. EVENT TECH - all cars must be comprehensively prepared prior to arrival at the track. At the track all entrants must pass a tech inspection of all car and driver safety equipment and meet all the safety requirements of the BMW CCA Club Racing Program.

B. Any vehicle deemed unsafe by BMW CCA Club Racing Stewards will not be allowed to compete.

C. TECH FOR RULES COMPLIANCE, WEIGHING - Tech Stewards may require onsite detailed tech inspection for rules compliance including weighing any car entered in a race and/or may announce detailed tech of entries in a specific class or classes at a race.

D. IMPOUND - In order to promote careful adherence by all competitors to the car classification and preparation rules, Club Racing Stewards reserve the right to conduct impound and inspection of the first three cars in any or all classes immediately at the conclusion of each race. Cars found to be at variance with the class rules will be denied their finishing positions, and the variances will be recorded in the individual log books.

E. Inspection by Stewards - Tech Stewards may request disassembly and inspection of any entered car to ascertain its compliance with these rules. If the car is found to be in compliance Club Racing shall stand the expense of disassembly, inspection and reassembly. If found not to be in compliance the competitor shall bear these expenses.

2. HELMETS rated with a SNELL automotive rating of SA-95 or newer are required. (Snell M rated helmets are not allowed). Drivers of vehicles without full windshields are required to have either a full-face helmet with shield in place or use protective goggles. It is strongly recommended that all drivers wear either a full-face helmet with shield in place or protective goggles. Driver information required on helmet: Drivers name, blood type, allergies, and date of last tetanus.

3. ROLL CAGES - all classes require full roll cages. A horizontal brace is required in the rear hoop. All cages must be mounted metal-to-metal, of approved materials and of proper size as listed in Appendix A. Side impact “doorbars” may be added to any cage and the drivers door panel may be modified or removed to accommodate them. Side impact bars may be bolt-in or removable configuration.

A. STOCK class roll cages shall be bolted or welded into the car, shall be contained entirely within the driver/passenger compartment, and shall include six (6) attachment points as shown in Appendix A. Two (2) additional bars may be extended from the front cage downbar to the front wheel well to protect the driver’s feet/legs. Carpet/padding may be cut for roll cage installation (installation MUST be metal to metal). Rear braces may pass thru interior trim panels. Cage tubing cannot be welded or bolted to the sides or roof and cannot be attached to stiffening devices in trunk or engine compartment.

NOTE: Stock class car cages may NOT include braces to the rear shock towers. The few cars that were approved with this configuration will be grandfathered and allowed to remain in Stock IF they submit documentation in writing to the National Technical Steward including copies of log books, etc. proving they had been authorized this construction for Stock class. The NTC will respond in writing; such authorization must remain in the car’s log book. Without such documentation cars will compete in Prepared classes.

B. PREPARED class - Main hoop braces may be mounted at the rear shock mounts/towers or suspension pickup points. Such rear braces may pass through any rear bulkhead or panel separating the driver/passenger compartment from the trunk/cargo area/fuel tank/fuel cell area, provided the bulkhead or panel is sealed around said cage braces.

C. MODIFIED and SUPER MODIFIED - cage construction is free provide it complies with the basic structure outlined in Appendix A.

4. SAFETY HARNESS - 5 or 6 point competition harness (with 2” sub belt), no more than five years old and meeting SFI-16.1 standards, properly mounted, are required. Harness cannot be mounted to the seat or seat rail. Mounting must be to the chassis backed by large diameter washers or to the roll bar. No two harness straps can be attached to a single mounting bolt. No Y-type shoulder harnesses are allowed.

The shoulder harness straps must be mounted such that the angle of the straps from the driver’s shoulders to the anchor point must not be above horizontal nor at an angle greater than 40 degrees below horizontal. The anti-submarine straps should be mounted such that they will not allow upward vertical movement of the lap belt due to “crushing” of the front seat cushion in any situation.

The design of some seats can, in many cases, render the shoulder harness straps ineffective as they slide from the shoulders under lateral loading. It is, therefore, mandatory that seats which do not allow the shoulder harness straps to remain on the shoulders in all situations be modified with a slot for the harness straps to pass through, or be replaced with a racing seat which has provisions for routing the straps. This is a mandatory modification which must be completed before the vehicle will be eligible to compete. A “sternum strap” or similar solution is allowed, but is not a substitute for proper shoulder strap arrangement

5. DRIVING SUITS - One piece fire retardant driving suit is highly recommended. (Minimum requirement: Two layer or one layer plus fire retardant underwear). Three layer or two layer with SFI rating of 3.2A/5 strongly recommended. Military flight suits are not acceptable substitutes for fire retardant driving suits.) Fire retardant socks and gloves are required. Driving shoes of a fire retardant material are strongly recommended. Tennis shoes with all leather uppers are acceptable. Drivers with mustaches and/or beards must wear a balaclava.

6. FIRE SAFETY - a 2 lb. or larger fire extinguisher with a 10 B/C rating, securely metal-to-metal mounted in the cockpit in a safe location, and reachable to the driver while seated and restrained, is required. An on-board fire system is strongly recommended. Cars competing in the Modified and Super Modified classes on full race tires, i.e. slicks, require on-board fire systems with a minimum of two nozzles. One for the engine compartment and one for the driver’s area. Cars with on-board fire systems require E decals. All fire bottle safety pins must be removed so that the system is ready to activate.

7. WINDOWS, WINDOW NET - Both front door windows must be completely down and an approved window net and attachment system fitted to the driver’s window area. The window net must be attached to the cage and NOT to the door. Holes must not be drilled in the cage to mount the window net. All window nets must be a minimum of 17”x21” and SFI 27.1 rated. Net design must allow for quick one-handed removal. The net must be mounted securely at the top or bottom with provision for easy removal at the opposite edge in the event of an accident. The use of plastic tie wraps or straps is not allowed.

Tinted REAR windows are specifically disallowed in all classes and their use is discouraged in all windows. OEM window tinting is allowed. The purpose of this rule is to address dark aftermarket tinting which causes real safety issues in driver awareness and communication.

8. OPEN CARS - ARM RESTRAINTS - open cars (incl. convertibles with top up or down or with hardtop) must be equipped with approved arm restraints.

9. SEATS, SEAT BACK BRACES -

A. SEAT BACK BRACES - Seat back bracing is required in all classes, attached to the horizontal tube on the rear hoop of the cage. Braces must either be bolted securely to the seat utilizing a metal plate of no less than 12 sq. inches to distribute the load, OR, if not bolted to the seat, a brace of similar minimum dimensions must be in contact with the seat back. Minimal energy absorbing padding is allowed between the brace and seat back. It is recommended that if not attached to the seat the brace be designed where possible to wrap around both sides of the seat to prevent lateral movement. Contact Regional Technical Stewards with any specific application questions.

B. REPLACEMENT SEATS - any replacement drivers seat must meet or exceed the strength and rigidity of the factory installed seat.

C. Hardware - the minimum diameter of all seat fastening hardware must be 8 mm. 2002’s, 530i’s and early 320i’s must upgrade the original 6 mm hardware. It is strongly recommended that the seat mounting pads on these early cars be strengthened to withstand the loads of racing.

D. Headrests, either integral with the seat or separate, are required. The headrest must extend above the midpoint of the back of the helmet on the vertical plane of the seatback with the driver in the normal seating position.

10. Neck Support - padded nomex covered neck supports are recommended.

11. Airbags and Steering Wheels - Non-standard steering wheels are allowed in all classes. Airbags may be disconnected during on-track sessions in all classes and may be removed from the stock steering wheel.

12. Rear Bulkhead - a metal bulkhead between the passenger compartment and the trunk or compartment containing the fuel tank is required on cars using a fuel cell or where the fuel tank is not totally under the car floor (ie: is required in 1600/2002 models). Such a bulkhead is recommended but not required on cars where the fuel tank is under the body (ie: E36).

13. Sunroofs must remain completely closed.

14. Floor mats must be removed. Drivers side carpet may be removed.

15. Hubcaps, trim rings, etc. must be removed.

16. Lugnuts must be original manufacturer specification with engagement at least equal to the diameter of the wheel lug studs. Use of wheel studs to replace lugbolts is allowed.

17. Oil lines - All oil lines on the pressure side of the oil pump must be thread-on connections equal to or better that the factory, i.e. NO slip-on oil lines to coolers, gauges, etc.

18. An electrical cut-off switch, with standard approved decal, mounted externally preferably on the drivers side - is strongly recommended for all cars and is required for cars competing in Modified and Super Modified classes on full race tires, i.e. slicks. The switch must disconnect the battery from all circuits, (except an electronically operated fire system) and must shut off the engine (and alternator) while it is running. Method of operation can be by pull wire, requiring no external body modification. (See Appendix C)

19. Catch tank for radiator overflow and oil breather (if vented into the atmosphere) is mandatory.

20. SOUND LEVEL - All competitors' cars must not exceed a maximum sound emission level of 105 dB as measured from a distance of 50 ft from the edge of the track. More restrictive standards may apply from track to track. Competitors bear sole responsibility to determine that their vehicles comply with Sound Control Regulations at each event. Mufflers may be required.

21. Engine Coolant - Use of an ethylene glycol (coolant) substitute (e.g. “Water Wetter”) is encouraged for all competitors. Ethylene glycol may be used when deemed necessary for climatic reasons.

22. PERSONAL MEDICAL IDENTIFICATION - Club Racing recommends use of personal medical information (worn by drivers) and endorses the TrakMed system (www.trakmed.com). The rules package will contain further information on the TrakMed product and a special BMW CCA Club Racing offer. For the 2001 series use of the TrakMed system or equivalent is strongly recommended. Your safety is our (and should be your) first priority!

Car Classification

Stock and Prepared Classes

1. General

Any vehicle in the stock and prepared classes must compete with full road equipment and, with the exception of exhaust/emissions, be street legal, and capable of being registered for street use in the condition of the car when presented at scrutineering, and be capable of being driven to and from the event.

Cars in these classes are to be factory equipped vehicles as delivered to the general public through United States dealerships. No special order performance enhancements are allowed as stock. Evolution parts are considered modifications and may only be interchanged with stock parts as allowed in class rules. Eurospec cars will be classified a minimum of one stock or prepared class up from an American spec model.

Vehicles competing in SCCA “Amateur” classes (Improved Touring, Touring 1, Touring 2 and Showroom Stock) can participate in BMW CCA Club Racing adhering to either BMW CCA class rules or SCCA class rules, but not a combination of both. Competitors must declare which series preparation rules they are complying with and be prepared to present the applicable rule book. Log books documenting participation in SCCA ITA/B/C/S, Touring 1 or 2, or Showroom Stock A/B/C classes are required for cars running under SCCA IT, Touring or Showroom Stock configurations OR entrants must conform to BMW CCA class rules. The logbook does not have to be current; documentation will be noted in the BMW CCA logbook. Stewards may allow a one time, one race exemption noted in the BMW logbook.

Cars complying with Touring or Showroom Stock specs will be classed in the appropriate Stock class. Cars complying with ITA/B/C/S specs will be classed in the appropriate Prepared class. ITE cars will generally be classed as Modified.

2. Approved Weights

STOCK AND PREPARED CLASSES - APPROVED WEIGHTS

All cars in the stock and prepared classes must meet or exceed the minimum weight as specified in Appendix E. The cars may be measured as they come off the track from qualifying and/or race sessions. A car found to be underweight after a qualifying session must add securely mounted ballast in the passenger compartment to meet the minimum weight requirement or choose to move to a higher class for that single event. The vehicle will be moved to the back of the starting grid for the race. A car found to be underweight after a race session will be disqualified from race results. A notation will be made on the current event page of the vehicle logbook. The car shall be weighed at the next event and meet minimum weight requirements before being allowed to compete.

Current weight limits are based on published BMW NA weight as stated in the owner’s manual for year and model of the vehicle. Competitors are requested to provide this information at the technical inspection.

Four door cars may remove weight to equal a two door car of the same engine displacement.

Stock Class vehicles are measured without the driver and must meet published BMW factory weight.

Prepared Class vehicles are measured with the driver in the vehicle and total weight must meet allowed weight.

For Prepared Class cars (ITA, ITB, ITC and ITS) for which SCCA has published minimum weights for 2002, those weights apply.

For endurance races, the minimum weight shall be measured with the lighter of the registered drivers in the car.

PROTESTS AND APPEALS

Protests

1. A protest shall concern a decision, act, or omission of the organizers, officials, car, driver, or other person connected with the competition, which is considered to be a violation of these rules, except that a protest against a refusal of entry or license certification shall not be allowed. Each protest shall be accompanied by a fee of $50.00 in cash or check.

2. Every protest shall be made in writing, specifying the protestee's car number, brief description of car, rules infraction with section number, etc. The protest shall be addressed to the Protest Committee and signed by at least one entrant. Protests should be submitted prior to qualifying or race sessions to allow proper reclassification, but must be submitted within 30 minutes of completion of the last timed run of the protested car. The fee shall be returned if, and only if, the protest is upheld; otherwise the fee will go to the BMW CCA Club Racing treasury.

3. The Protest Committee has the right to impound any car(s). It is the driver's responsibility to present his car as required. The car must remain unchanged until released by the Protest Committee.

4. Only another driver in the same class can protest a car. The protester may request that the car be dismantled, inspected, or any other test made, provided that, if a driver, they post a cash bond with the Protest Committee sufficient to cover the total expense of disassembly, inspection and reassembly. If the car shall be found upon inspection to conform to the rules, the protester shall forfeit the bond which shall be used to cover costs involved. If the car is found upon inspection not to conform to the rules, the protester's bond shall be returned and the driver of the protested car shall stand all expenses and be subject to penalty.

5. The Protest Committee shall hear the arguments of the protestee and the protestor, and by majority vote, shall determine the validity of the Protest and shall determine penalties for upheld protests which are appropriate to the seriousness of the offense. It is not necessary that every protest result in disqualification. The Protest Committee may deny any protest deemed to be spurious or a nuisance, particularly if it concerns non-performance affecting items. If a car is found to be improperly classified or to have unauthorized modifications, any penalties shall be assessed against all drivers of that car.

6. The event’s Club Racing Competition Steward shall be the chairman of the event Protest Committee, and shall appoint two other committee members, one of whom may be the event’s Technical Steward, shall appoint alternates, and shall prominently post their names at the event. The alternate(s) will act as a committee member if any member is involved in the protest or may otherwise have conflict of interest, or is not available.

Appeals

1. Decisions of the Protest Committee or 13/13 Penalties may be appealed to the Club Racing National Committee, consisting of the National Competition Steward and National Technical Steward, one Regional Competition Steward, one Regional Technical Steward, and one Advisory Committee member. An appeal shall be in writing, addressed to the BMW CCA National Competition Steward, shall be accompanied by a $50.00 appeal fee, and shall reach the National Competition Steward within 14 days after the protest or 13/13 decision. It must specify the grounds for appeal and must contain the information that the appellant wishes to be considered in the appeal. The Club Racing National Committee will make the final decision whether or not the appeal is well- founded and should be heard, and whether the appeal fee should be returned or forfeited. Said decision shall be final, binding, and not subject to appeal. The fee shall be returned if the appeal is resolved in favor of the appellant, otherwise the fee will go to the Club Racing treasury. Any committee member who was involved in the initial protest or 13/13 penalty or may otherwise have a conflict of interest may not participate in the appeal discussion or vote. Appeal decisions will be decided by majority vote.

Rules Process

Rules Clarifications

1. The purpose of a Rules clarification is to resolve questions about the rules without recourse to an official protest against one entrant by another.

A. A rules clarification shall be made by the Club Racing Rules Committee.

B. A request may be made by any BMW CCA member who has entered a BMW CCA Club Racing event within a year prior to the request .

C. A request for Rules Clarification shall be submitted in writing to any member of the Club Racing Rules Committee. The request shall cite the paragraph in question and shall be signed by the requestor.

D. There shall be no charge for the request.

E. A written reply shall be sent from the Club Racing Rules Committee to the requestor within 30 days of the request.

F. A written Rules Clarification from the Club Racing Rules Committee is considered part of the current year rules and therefore may be used in future protest action. Such clarification shall be effective 30 days after publication and expire with publication of the next year’s rules.

NOTE: Informal questions from current or prospective racers are welcome at any time. The Rules Clarification procedure facilitates formal inquiries or requested changes to the current rules.

Rule Changes

This section describes the method for updating and changing these rules. The Club Racing Rules Committee is responsible for this process as detailed in the following paragraphs. Ordinarily, there will be only one set of rules changes per year as specified below. These will become effective at the start of the next calendar year's season. Rules changes at other times are also specified below.

Club Racing Rules Committee

The Club Racing Rules Committee is comprised of the Club Racing Chairman, the National Competition Steward, the National Technical Steward, and one representative of the Club Racing Advisory Committee (CRAC) appointed by the CRAC. The CRAC will officially advise the Club Racing Chairman of its representational appointment by February 1 of each year. The appointment will continue until the end of the calendar year or until officially rescinded by CRAC. Should CRAC fail to make the appointment of their representative in a timely fashion, the Rules Committee is explicitly empowered to conduct all business normally attributed to the committee.

Rules Change Calendar

Prior to July 1 of each year, licensed Club Racing participants shall be invited (by CR newsletter or other means) to submit written requests and suggestions for rules updates for the next calendar year. The Club Racing Rules Committee shall review this input and, from these and other sources including the Club Racing Advisory Committee (CRAC), shall prepare a set of proposed rule changes. This proposal shall be published and distributed to licensed Club Racing participants, along with a request for comment.

Utilizing the responses, the Club Racing Rules Committee shall finalize and publish the rules changes.

July 15 - deadline to send rules change proposals to the Club Racing Rules Committee.

September CR newsletter - proposed changes available for Racer comment/input.

November CR Newsletter - final rules changes posted on website. New rule books printed and distributed.

Changes in Mid-year

In exceptional circumstances it may be necessary to make rule changes

in mid-year. For such changes, the Club Racing Rules Committee shall prepare a change proposal and review it with the CRAC. Based on the comments received, the Club Racing Rules Committee shall finalize the change and the rule change shall become effective on the date specified.

Club Racing Advisory Committee (CRAC)

The Club Racing Advisory Committee (CRAC) is comprised of licensed BMW CCA Club Racers chosen yearly by a vote of the Club Racing participants from each region of the country. The regions are defined to be the same geographical areas as those defined for BMW CCA national regions. The elected CRAC representatives shall serve a term of two years.

In the event of the resignation or other departure from service by any CRAC member, the Club Racing Chairman shall solicit volunteers from within the affected region. The Club Racing Chairman will appoint a replacement from the volunteer pool. The appointee shall fill the position until the next election cycle.
APPENDIX A - Roll Cage Specifications

All vehicles competing in the BMW CCA Club Racing program must be equipped with an approved roll cage. The main (rear) hoop must be securely mounted, either bolted or welded, to the floor and/or longitudinal members of the unibody with the top of the main hoop as close to the roof as possible in closed cars and at least 2” above the drivers helmet when the driver is seated in the normal driving position in open cars. The mounting area of the “bolt-in” roll cage must be backed by a plate of a size equal to that of the upper mounting plate with a minimum thickness of 3/16”. Bolts must be grade 5 or higher. The roll cage must be mounted directly to the metal of the chassis and any padding, carpet, upholstery, etc., must be removed to satisfy this requirement. The roll cage must be full cockpit width, except as originally supplied by the factory for open race cars, and have two fore/aft braces of tubing size equal to the main hoop. The brace must be mounted as near the top of the hoop as possible and at an included angle of at least 30 degrees.

Additionally, the cage assembly must contain a transverse (horizontal, left to right side) brace which can be used for seatbelt harness mounting and as the attachment point for the seat back brace. An inspection hole 3/16” in diameter must be provided in a non-critical area for verification of tube thickness. Any portion of the cage which may come in contact with the driver’s helmet must be covered with high density foam 1” thick held in place with electrical or duct tape or tie wraps.

The main and front hoops and fore and aft braces must have the following minimum diameter and wall thickness:

Under 2500 lbs Over 2500 lbs

Mild Steel 1.5” x .095” 1.75” x .095” or

1.50” x .120”

Alloy Steel 1.375” x .095” 1.50” x .095”

Other components of the roll cage need not have the same diameter and wall thickness as that of the required components.

FIA approved roll cages with manufacturers certificate of approval are allowed.
It is strongly recommended that an experienced roll cage constructor be consulted in the cage design and installation. Any questions contact a BMW CCA Club Racing Technical Steward.

APPENDIX B – Electrical Disconnect Specifications

A standard electrical disconnect (battery cut-off) switch is strongly recommended on all cars competing in the BMW CCA Club Racing program and required for cars competing in Modified and Super Modified classes on full race tires, i.e. slicks. This switch must be wired such that electrical power to all circuits including alternator, except an electrically operated on-board fire system, is disconnected. In the interest of convenience, the switch may be mounted in the compartment near the battery and operation effected by a pull wire passing to the outside. The preferred location of the pull wire is on the driver’s side. It must be clearly visible and its position marked with an approved decal of “lightening bolt” and the word “OFF”. The decal can be placed on the window glass as opposed to the bodywork, as close as possible to the pull wire. It is recommended that the pull wire be painted red for visibility. Those vehicles with a permanently mounted switch or pull wire in another location will be allowed that alternate location providing the position is clearly marked with the approved decal and the switch or pull wire is easily accessible from outside the vehicle.

This requirement does not have to be viewed as a difficult one with which to comply and can very easily be accomplished with the fabrication of a simple bracket to hold the switch near the battery. Braided wire can be used for the pull and it should pass through a small bracket mounted inside the compartment. A loop in the end of the cable completes the installation. Pulling the cable rotates the switch and disconnects the battery from the circuit.
