Hey Challenger pilots, want to get some opinions. 2months ago I bought a 2010 SRT8, and plan on a lot of autocross and a few road courses a year. The car came with the stock 20X9 aluminum rims and it has 245/45R Falken street tires on it. I already purchased a BC coilover setup, rear sway bar, and front and back strut tower braces for it. What I'm trying to figure is if it'll be good/necessary to change wheel size, for running a set of treadwear 200 tires on it. I'd really appreciate some experienced voices here. Thanks! And I'm glad to be on the site!
