307s basically have the same braking setup - 283mm rotors up front and the base rim is 15", so you can take 15s if you want.Zen said:Definitely going some semi slicks and track use rims, gonna have to be 16"'s though, pretty sure the brake rotors and calipers won't fit inside a 15" rim. 306 GTi6 have 16"'s, right? If so anyone have a set they want to sell?
