what 15" racing wheel will fit?
running a 15" wheel in the back of the fbody
15" x 7" w/4.5" backspacing
15" x 8" w/5.5" backspacing
15" x 10" w/7.5" backspacing
it will require a large amount of grinding of the rear calipers to clear the wheel. here's pics of what i had to do to mine. scroll to the bottom.

one thing to remember, if you do your grinding with half worn brake pads, when it comes time to replace them, the wheels may hit again. the thicker the brake pads, the further outward the caliper moves.
i encourage others to show what they put on and needed to do to get them to fit.
