The Pro Slammer 7 Second Door Car Association was created by Mike Doushgounian and Dana Wardell. The PSDCA is an association that provides an alternative class for racers stuck in the middle of pre-existing classes which prevent them from being competitive with their current racing combination.

The Pro Slammer 7 Second Door Car Association is the working man’s association and was designed with the working man in mind. With any domestic body style and any engine combination allowed, the Pro Slammer 7 Second Door Car Association provides one of the most affordable and exciting classes for spectator's, media groups, and racers.

Using a heads-up start on a four-tenths pro-start format. The 7 second door cars are the most exciting to watch as they provide close, side-by-side racing that is fun to watch and easy to understand from the spectator's view point.
