Tire Rack CAM Challenge Series Powered by SCCA

"America's Pro-Touring Autocross Championship Series"

Rumbling V8 engines, ground-pounding American muscle – these are the characteristics of Classic American Muscle cars, or as they are known in SCCA® Solo® – CAM cars.

These muscle cars which are so popular at the fancy auctions have also found a home in SCCA® fulfilling their purpose – getting them out of the garage and being pushed to their limits of something other than gathering dust.

SCCA has three classes for these types of cars – CAM C, CAM T and CAM S.

  • CAM C: With the “C" standing for Contemporary, this class sees car and truck body styles from 1990-on, plus CAM T class cars. (Minimum weight w/o driver is 3300 lbs.)
  • CAM T: In this case, the “T” stands for Traditional, and this class is for car and truck body styles originating from 1954-89. (Minimum weight w/o driver is 3000 lbs.)
  • CAM S: The “S” stands for Sports and this class is where sports cars, sedans/coupes, and trucks with seating for 2 or more adults. (Minimum weight for 1984+ Corvettes and Vipers is 2900 lbs. Minimum weight for all other cars is 2500 lbs.)

For 2019 there will be a CAM Challenge Series with events around the country with Challenge Champions crowned in all three CAM classes and an Overall CAM Challenge Series Champion crowned in Lincoln at the 2019 Tire Rack SCCA Solo Nationals.
