Local honda road race/autocross class?

I’m actually thinking I’ll be stuck in SM until I get some sort of spoiler, you can add one, change one, but can’t take one off apparently?

And what would move me from BSP instead of STU? engine management? Everything I see in STU basically seems to fit with my car, except the wing.

I’m garaging my car right now, not to baby it, but to do some suspension work, can’t wait to get it out next year.
