Does anybody know the wheel or rims specs on a 96 pontiac formula? I want to put on some 18 x 10.5 in the rear and 17 x 9.5" Silver Corvette C6 wheels / Machined lip in the front. I am wondering if the Rear 18 x 10.5 / 54mm and front 17 x 9.5 / 56mm fit? I think the car would look great with 18's...
