We just checked, and Suzuki pays contingency in both the MWSS & HWSS classes on racing slicks in the USBA, as well as other contingency. They would pay in OSS, but that class does not exist in USBA. Specific class rules for the particular organization seem to have little to no bearing on manufacturer or parts contingency offered, as long as the overall definition of Superstock / Supersport exists. This is the case nationwide.
