Does anyone run in this class? At the last SFR round, I wasn't able to keep up with the guys running R-compund tires. But I was the fastest car running street tires in ESP.

Should I switch to the Street Tire-Street Prepared class?
(There was only one car running in that class last round and I think I was faster than him.)

 

I might not understand the question. Aren't you running now in a SP class? If you are, your local region makes a distinction between street tire and r comp SP classes? What is your goal? Have fun, be competitive locally?
