to try and help the sale of these wheels, here is a
WHEEL FITMENT CALCULATOR. Top set of data is for current setup (width and offset), bottom is obviously for future setup. Hit calculate and it will tell you how much more room is taken up, or given up behind the wheel, and how much more it will be pushed out.
good luck again man, although i say keep em if you've already done the body work and what not on ur Supra...
