okay so i picked up a set of ZR1 wheels for stupid cheap and now i need to mount them to the car. i read most people have the 17x9.5 with a 50 mm offset well mine are stamped 54 mm offset. i did the calculator from skulte and i get 2.12 front and 1.27 rear ( i have done it over and over and over again ) now what i need to know is obviously the 2" spacer is too small so what i need to know is will the 2.25 front and rear fit the car okay or will they stick out too far? 86 trans am with an 88 posi 3.27 9 bolt rear. i need a quick answer if possible

 

I hope my mind is not going back but I think the older F-body rears are narrower than the later ones, which these fit just fine.

Is your 9 inch rear made to the same width spec as stock?

 

stock third gen yes
