I am looking for a wheel/tire set-up for my '01 GT for track use only (1/8th mile). I am considering 15 x 10 with 6.5 backspace Weld Drag Lites. Do I need the XPs or will the regular ones work with GT brakes? What about the fronts? What offset is needed there? For tires I was looking at 28 X 10.5 X 15 MT ET Drag slicks or 275/60/15 MT ET Drag radials. The car makes 500rwhp, has an automatic and a 410 gear. Any recommendations? I also like the looks of the Center Line Telstars but their catalog doesn't list anything with a 6.5 backspace? I really like the look of the new MT ET wheels - but unfortunately MT likes them even more than I do! They are a little bit pricey! The Weld Magnums also look good.
