Stock Division: If upon measuring, any stock car that is found to have the front kingpin greater than 7-15/16” from the front center of the floorboard to the center of the front kingpin, the floorboard is now considered illegal and can no longer be used.
Stock Division: The center of the front king pin to the center of the rear king pin is 61-1/8”, with a tolerance of +/- 1/16”. If upon measuring, these conditions are not met, the floorboard is now considered illegal and can no longer be used.
Super Stock Division: If upon measuring, the front kingpin is found to be greater than 5 13/16” from the front center of the floorboard to the center of the front king pin, the floorboard is now considered illegal and can no longer be used.
Super Stock Division: The center of the front king pin to the center of the rear king pin is 63 3/8”, with the tolerance of +/- 1/16”. If upon measuring these conditions are not met, the floorboard is now considered illegal and can no longer be used. The rationale behind this phase out period is listed below:
- (1) Racers were permitted to re-drill their king pin hole in order to install the bushing
- (2) Some racers have taken advantage of the opportunity to re-drill the king pin hole and as a result have moved the hole closer to the rear of the car.
- (3) With the above occurring, this has created an unfair advantage to the racers that installed their bushing properly and are racing with floorboards manufactured after 2005.
