Cars like we have are not going to fit in any road race class. So you run them at track fun-day events. You can run the same car you autocross with, just take some rear roll resistance out, like rear sway bar). And IF you autocross with “autocross only” tires, you would not run those of course. And you’d have other tires anyways.
unless you build a trans am repli-car that’s a full caged race car with trailer type deal...VARA, SVRA etc type events.
