BMW CCA CLUB RACING - 2000 RULES
Modified & Super Modified Classes
Appendix A - Roll Cage Specifications
Appendix B - Seat Belt Specifications
Appendix C - Electrical Disconnect Specifications
Appendix D - Window Net Specifications
The overall philosophy at each BMW CCA Club Racing Event will be the same:
"A competitive driving experience for all BMW CCA enthusiasts, in any/all types of 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 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 driveable and in keeping with the spirit of the "original" vehicle.
MODIFIED AND SUPER MODIFIED - Those wishing to build full blown" race cars 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 pro series cars (i.e. Super Touring, SCCA World Challenge cars).
1. 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 for the event.
7 - any racer currently on probation MUST attend any/all scheduled "Rookie" meetings at the next race they participate in.
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:
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 ontrack incident causing visible damage to their or another driver's car must report to the event Technical Steward with the car (if driveable) 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.
3. Only BMW CCA Club Racing Program "licensed" drivers are eligible to compete.
4. Any modification not specifically listed is not allowed. In other words, if the rules dont say you can do it - DONT.
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. Only BMW manufactured automobiles, using BMW manufactured chassis, engine case and transmission case, and factory approved race cars and modifications are eligible. (Documentation of factory approval is the responsibility of the car owner). Tube frame construction cars are allowed in modified classes.
7. CAR NUMBERS, CLASS IDENTIFICATION, DECALS:
B. Competitors may request assigned numbers from the National Registrar. The goal will be to allow racers to use requested numbers. Where duplications exists, 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. 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. The 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. BMW CCA Club Racing National officials reserve the right to reclassify a car and driver based upon a review of previous performance.
10. 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.
11. Vehicles must compete in the class to which they are classified to be eligible for awards.
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.
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.

Mufflers may be required.
21 - 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 2000 series use of the TrakMed system or equivalent is strongly recommended.
Your safety is our (and should be your) first priority!
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 IT, Touring or Showroom Stock 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 log book.
Cars complying with Touring or Showroom Stock specs will be classed in the appropriate Stock class.
Cars complying with IT specs will be classed in the appropriate Prepared class.
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 owners manual for year and model of the vehicle. Competitors are requested to provide this information at the technical inspection.
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.

Modified & Super Modified Classes
Allowed modifications in addition to those allowed in Stock & Prepared Classes
Introduction
Any car which exceeds the modifications for the "STOCK" and "PREPARED" classes will compete in either the MODIFIED or SUPER MODIFIED CLASSES. The cars in these classes do not have to be street registerable, however, they must meet accepted safety requirements and the decision to be allowed to run rests entirely with the BMW CCA Club Racing Program personnel. Class for competition will be based on engine displacement.
Modified class is intended for the SCCA GT class car competing at the regional level of preparation which is designated for the amateur level and for cars that exceeds the level of modifications in the Prepared class.
Super Modified class is intended for the pro series cars that were built to compete in various professional racing series (i.e. IMSA GT, Super Touring and SCCA World Challenge etc.). The Event Stewards have the final decision on classification of entries as Modified or Super Modified, subject to appeal.

Protests
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 unauthorizedmodifications, any penalties shall be assessed against all drivers of that car.
6. The events 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 events Technical Steward, shall appoint alternates, and shall prominently post their names at the event.

Appeals
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 National 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 National 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 National Committee to the requestor within 30 days of the request.
F. A written Rules Clarification from the Club Racing National 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 years 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.
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 by 7/1 and serving until 12/31 of the calendar year.
Club Racing Advisory Committee (CRAC)
The Club Racing Advisory Committee (CRAC) is comprised of members 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.
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 printed and available for Racer comment/input..
December CR Newsletter - final rules changes printed. 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.
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 at least 2" above the drivers helmet when the driver is seated in the normal driving position. 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 drivers 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.
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 - Seat Belt Specifications
ALL cars competing in the BMW CCA Club Racing Program must be equipped with a five or six point harness system, no more than 5 years old and meeting SFI-16.1 standards. For all systems other than Schroth (see below) the lap belt is required to be 3 inches wide and shoulder straps can be 2 inches wide, although 3 inch straps are strongly recommended. The anti-submarine belt may be 2 inches wide. The Schroth Profi II Competition Restraint System is approved as a 2" lap/3" shoulder configuration which meets SFI-16.1 standards. The shoulder harness straps must be mounted such that the angle of the straps from the drivers 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 will not be allowed!
Appendix C - 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 drivers 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 (see illustration).

Appendix D - Window Net Specifications
All vehicles competing in the BMW CCA Club Racing program must be equipped with a window net covering the drivers window of either the string or strap type. 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.
Net design must allow for quick one-handed removal. For cars with cages/door bars the window net must be attached to the cage and NOT to the door.
