SUSPENSION:
Stock style suspension cars only. Aftermarket bolt-on replacement front K-members are allowed (if front shocks bolt to K-member then they must be in factory location). For 1974 and earlier model years, OEM strut tower/shock tower may be removed in lieu of installing/using commercially available suspension kit. (IE Heidt, Fat Man, Alston, Smith Racecraft etc)with a 50 pound weight adder. Other sections of front suspension rules must be adhered to.
Mini tubs are allowed. Stock unaltered frame rails required in front sub frame. Stock rear sub frames are required, but outer frame rail portion only may be notched for tire clearance only. When notching, stock inboard section of rear frame rails must remain stock, unaltered, and in stock location. Rear frame rails must remain in OEM stock condition in all areas. Four links and back half cars are prohibited. Aftermarket direct replacement components such as: front control arms, rear control arms, front coil over shocks, and rear coil over shocks are permitted. Aftermarket rack and pinion steering permitted. Bolt-on or welded sub-frame connectors, rear sway bars, are permitted on all cars. Torque arms are only permitted on cars that came originally equipped from factory (with exception of IRS conversion cars). Cars originally equipped with rear wheel drive Independent rear suspension will be permitted to convert to solid axle and OEM design torque arm i.e., Corvette, GTO, 5th Gen Camaro
Can there be an addition to the rule allowing ladder bar cars with stock floors and frame rails? Coil overs are already allowed (front and rear). Front clips are already allowed for the older cars.....with a weight penalty. Don't see any real advantage with the ladder bar over a F-body car's torque arm set up,,, may open the class attendance up a bit recruiting some older bodied cars in.
