go staggered with the H&R Springs do your 245/45 17's with 9.5 in the front and the 375/55 17's with a 10.5 in the back it gives the car that old school muscle car look and eliminates the need for wheel spacers...i ran this setup on my 95gt and my wheels sat flush with the rear quarter and didnt rub at all plus it gets rid of that ugly inset you see between the quarter and the tire when on factory wheels
