I know the 5/16" spacer is the norm for F-bodies running the 15x3.5" Weld Front Runners. Does a different size spacer need to be run if you've upgraded your front brakes to the C5 rotors (12" diameter) from the stock F-body rotors (11" diameter)?

anyone feel free to correct me if i am wrong, but with C5 brakes you need to have at least 17" wheels, 15" front runners are a no go with C5 brakes. I have 17" TTII's on the front with c5 brakes and its a tight fit...... Assuming you are going with C5 Rotors and Calipers.....

You are correct, but skinnies don't go around the brakes like street wheels do.

I'm just trying to figure out if I need more of a spacer than 5/16".
