Cal Club Autocross Forums

Hey all. I'm kinda new to this, and I want to make sure I don't sign up for the wrong class. Here's my car: Car: 300hp BMW 135i (twin turbo) Street Tires (not stock, but still street tires) Mods: Dual Cone Intake (doesn't add any power but makes the turbos go whooosh!) What class does that put me in?
