A simple rule I was taught it that you measure the distance from the center of your hub to the outside of you rotor. Your wheel needs to be 2 inches larger on average. Mine are 15.5 up front and that means an 18 is needed.
Thanks man...I haven't decided yet. More than likely the race line since they are the lightest with titanium hardware. Considering having Ben Hermance re render a few options.
Your present rims look on your car now. I would problably stay with the brushed centers and polished or chrome lip.
I really like the Forgelines on the project "re-peeled" I know they are a different style...but a red stripe around the rim for your car should would be cool.
