Crossover Rules

The crossover classes below run under their own set of class rules and ignore the WCF rulebook. You must be legal with your rulebook unless there is as a parity adjustment in the table below. In some cases, a crossover class may need an adjustment to be sped up or slowed down to make parity at WCF. If your car fits multiple crossover classes, then choose the one gives you the most advantage.


Engine Containment Device

Engine diaper or catch pan device to capture oil and/or debris is mandatory. If a catch pan device is used, catch pan must have a minimum 2-inch-high lip on all sides. Lips must be covered or curved inward, so as to contain oil in pan. Catch pan must cover entire area below the engine. Catch pan must extend from radiator support to firewall and from frame rail to frame rail. In all cases, lips must be adequate enough to contain oil in the catch pan. Should a competitor spill excessive oil from the catch pan and debris onto the track, he or she may be disqualified from further competition at the sole and absolute discretion of the event director.
