The Car

Class 11 is limited to pre-1983 Volkswagen Beetles and allows for minor modifications to the engine, transmission and suspension. You can buy a race-prepped Class 11 for $7,000, but truly competitive cars cost quite a bit more. As one racer told us, “The secret to winning in a stock class is to be as un-stock as possible.”
