So no go on the offset? Only reason I’m doing this is that we had a 1995 GT 5.0 come in with 26k miles on it. Mint 3 brand new Bf Goodrich tires in that size specs. The 4th was damaged in the accident.. I have (2) Bf Goodrich 255/40/17 in the rear and (2) continental pro contact sports for the front. I plan on lowering the rear and the front with the front being slightly lower 1/2 inch or so. Spacers on the rear. I have 4:10 gears, off road H pipe (full cat delete), hurst short throw shifter kit and a Mach 1 chin spoiler ready to go in as soon as the salts off the road and I can get it down to the shop.
