Future Manufacturer Contingency Programs

SCCA has made the initial classifications allowing competitors to utilize any shock and spring that meets basic requirements. Please note that future manufacturer contingency programs may require you to purchase their shocks and springs to qualify for their programs.


Future Plans:

2011 Race Season:

- The B-Spec cars are classified in SSC. A B-Spec driver can attend the Runoffs as an SSC car if the Runoffs qualification requirements are satisfied.

2012 Race Season

- Same as 2011

- Additional cars will be classified as they become available and specifications are provided
