On the front I used two of the stock 235/55's on 17x8's and I put 285/40 P-Zero Nero's on 18x8.5's on the rear. The wheels are Konig Imagine.
More mods? Definitely. All I have right now is a Magnaflow exhaust. I'm holding off on some of the other plans (CAI, etc.) until the Whipple blower kit comes out. I want to shove 6-7 psi down her throat!
