Lips must be coved or curved inward, so as to contain oil in pan. Catch pan must cover entire area below the engine/transmission. 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 until the catch pan is upgraded, regardless of the height of pan lips or pan design.

All drivers running 10.00 seconds or slower must have a valid state- or government-issued driver’s license beyond a learner’s-permit level or valid NHRA competition license.
