The SSSCC uses SCCA Solo rules for vehicle classing. Because the SSSCC is a smaller club, they decided to group the large number of SCCA classes into smaller class groupings. This provides larger class sizes for better competition. So you must determine your SCCA vehicle class to determine what SSSCC class you can run in. In addition, the SSSCC uses a Street Tire Multiplier for any of the Non-Stock classes. This additional multiplier of .980 allows drivers to compete on either DOT R-Compound race tires (Hoosier A7, Kumho V710, BFG R1-S) or their choice of street tires (street tires must have a tread wear rating of 200 or greater).
