Drive-shaft loop


For cars with driveshafts that contain universal joints: For all full-bodied and open-bodied cars running between 7.50

Battery Relocation


If the battery is not in the stock location, and relocated to the trunk, for example, you must have an external cut-off switch on the back of the car which cuts off the electrical system and must also stop the car from running.
 

Seat Belts


All cars must be equipped with an accepted quick release type driver seat belt. All cars in competition requiring a roll bar or roll cage, or as outlined by Class Requirements, require a Driver Restraint System as outlined below.
 

Driver Restraint Systems


A quick-release, 3-inch shoulder harness meeting SFI Spec 16.1, including crotch strap, is mandatory in all cars in competition required by the rules to have a roll bar or a roll cage. Driver restraint system must be clearly labeled as meeting SFI Spec 16.1 and be dated by manufacturer. System must be updated at two-year intervals from date of manufacture. All seat belt and shoulder harness installations must be mutually compatible, originally designed to be used with each other, and produced by the same manufacturer. Cars using OEM or OEM type seat may route crotch strap in front of seat instead of through seat. Only those units that release all five attachment points in one motion are permitted.
When arm restraints are worn with a restraint system that utilizes a "latch lever", a protective cover must be installed to prevent arm restraint from accidentally releasing the latch lever. Protective cover not needed if system uses "duckbill" latch hardware. All harness sections must be mounted to the frame, cross member, or reinforced mounting, and installed to limit driver's body travel both upward and forward. Seat belts may not be wrapped around lower frame rails.
Under no circumstances are bolts inserted through belt webbing permitted for mounting. Check manufacturer’s instructions.

 

Wheels & Lug Nuts


All wheels must have ALL lug nuts in place and securely fastened. All street tires must have minimum 1/16 inch tread depth.
Vehicles with slicks must have open ended lug nuts. The thread engagement on all wheel studs to the lug nut, or lug bolts to wheel hubs, must be equivalent to or greater than the diameter of the stud/bolt. Length of the stud/bolt does not determine permissibility. (Example: A 7/16-inch stud must be thoroughly engaged through the threads in the hex portion of the lug a minimum of 7/16-inch.)
