Since your car fits in a stock PCA class why not do both?
You could race with PCA regionally next season at Road America, Gingerman and Putnam Park.
You could still do the HPDE's you've been in. That's what I would do in a second if my car fit into a class that I could be competitive in. Sounds like you're having second thoughts after what happened last weekend at RA? I don't blame you. It was a reality check for everyone there. Since my race car is turbo charged I get bumped into GT-1 in PCA or I would do both.....I don't want to be a target in that group. You're fast enough not to be a target in your class and a good driver Glenn. I'd give it a shot.
