The overall philosophy at each BMW CCA Club Racing Event will be the same:

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).

competitive. Good sportsmanship, honesty, and a sense of fair play should

exist at all BMW CCA Club Racing events.

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

3. Subject to suspension from the next BMW CCA Club Racing event in

which they could have competed.

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

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

for the event.

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

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. The Appeals process is available to racers if there is ADDITIONAL specific video or mechanical evidence or competitor information that was not presented or available at the event which strongly suggests a revised decision is warranted.

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 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. 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:

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

B. Competitors may request assigned numbers from the National Registrar.

C. Club Racing officials may require series and sponsor identification

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. 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.

11. 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.

12. Vehicles must compete in the class to which they are classified to be eligible

for awards.

1. TECH INSPECTION, ANNUAL TECH

technical inspection. Procedures and required documentation will be

provided to all licensed racers.

B. 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.

C. Any vehicle deemed unsafe by BMW CCA Club Racing Stewards will not

be allowed to compete.

D. 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. If teardowns are required to validate rules

compliance or as a result of impound they are at competitor's expense.

E. 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 each

class 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.

2. HELMETS rated with a SNELL automotive rating of SA-90 or newer are

required. (Snell M rated helmets are not allowed). Drivers of vehicles without

full windshields are required to have either full face helmets with shield in place

SUPPLEMENTAL CAGE SPECIFICATIONS - additional to the main cage, two supplemental mounting points may be added between the front hoop and firewall

to add protection to the leg and feet area in the event of a side impact.

These mounting points, bringing the total maximum mounting points allowed in STOCK or PREPARED to eight, may not pass through the firewall in prepared

class. Side impact "doorbars" may be added to any cage and the drivers door

panel may be modified or removed. These side impact bars may be bolt-in or removable configuration.

MODIFIED class roll cages may extend from "bumper to bumper" inside the

original bodywork. All cages must be mounted metal-to-metal, of approved

materials and of proper size as listed in Appendix A.

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 angle of the shoulder harness cannot be above nor exceed 40 degrees below the horizontal plane of the shoulders.

Modifications to or replacement of the driver’s seat may be necessary to meet this requirement. If the height or width of the seat back prevents the shoulder harness straps from remaining securely on the shoulders in all situations, the seat must be modified to remedy this condition. (See Appendix B)

5. DRIVING SUITS - One piece fire retardant driving suit is highly recommended.

(Minimum requirement: Two layer or one layer plus fire retardant underwear.

16. 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

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.

of the BMW CCA Club Racing Program, i.e., it is aesthetically pleasing.

H. Electrical disconnect is required for cars competing on full race tires,

i.e. slicks. See Appendix C for detail.

This class is designed to be run under vintage "exhibition" rules as a separate

race group if a sufficient number of entries and available scheduling allow.

Eligible open wheel cars would be permitted in this class.

Cars in this class may be exempt from some safety regulations found in other

racing classes, but will still be required to undergo a compete tech inspection.

Passing will be held to a minimum, only in designated zones and only with

proper signaling from the driver of the car being overtaken.

Drivers must meet all series standards for licensing and safety equipment

The decision to be allowed to run in this class rests entirely with BMW CCA

Club Racing personnel.

NOTE: For STOCK and PREPARED CLASSES the number of cylinders shall agree with the body type. For the MODIFIED CLASSES, displacement shall be no more than .75L larger than original for the stated model, exclusive of the turbo multiplication factor.

the protest is resolved. Any decision made by the Protest Committee will take

effect instantaneously but will not affect any prior activity of the vehicle.

Sessions completed prior to the Committee's decision shall stand.

5. 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.

6. 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

tems. 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.

7. 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 a member is involved in the protest or may otherwise

have conflict of interest, or is not available.

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 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 who has conflict of interest, with the

exception of the National Competition Steward and Technical Steward,

may not participate in the appeal discussion or vote. Appeal decisions

will be decided by majority vote

without recourse to an official protest against one entrant by another.

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.

E. A written reply shall be sent from the Club Racing National Committee

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 year’s

rules.

This section describes the method for updating and changing these rules.

The Club Racing 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.

The Club Racing Committee is comprised of the Club Racing Chairman, the

National Competition Steward and the National Technical Steward.

The Club Racing Advisory Committee 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.

All vehicles competing in the BMW CCA Club Racing program must be equipped with an approved roll bar. The roll bar must be securely mounted 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 bars 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 bar 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 bar 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 roll bar assembly must contain a transverse

(left to right side) 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 roll bar

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.

Minimum Tubing Sizes

For cars with roll cages, the main and front hoops and fore and aft braces must

have the following minimum diameter and wall thickness’:

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

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. The lap belt is required to be 3 inches wide. The shoulder straps can be 2 inches wide, although 3 inch straps are strongly recommended.

The anti-submarine belt may be 2 inches wide. 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 will not be allowed!

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 (see illustration).

All vehicles competing in the BMW CCA Club Racing program must be

equipped with a window net covering the driver’s 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.
