For purposes of points within a class, yes, all street tire drivers are together in one class labeled 'Street Tire'. However, within this class, each sub-class (i.e. A-stock, B-stock, etc.) has a different PAX factor. Therefore, if you ran a course in 1:00 min., and your PAX factor is .798, but a street tire Miata ran the course faster at 0:59, but has a PAX factor of .812 because their car is sub-classed differently you'd have the lower time of the two.

If you raced with performance tires and went into a non-street tire class - you'd be up against other cars that the SCCA has deemed similar to yours. For example, D-stock also has the Integra type R, Mini S, Audi TT and a few others. (Early in 2002, we had an Integra driver who killed the WRX's times but then he dropped out 1/2 through the season.)

Hope that helps.
