Wheels and TiresNeed help with wheels or tires? Got fitment issues? Have questions about tire performance and handling? Ask all of those questions here!
Hey everyone, Not a wheel tire geek, haven't found anything I can rely on with wheel sizes during a short look, I'm looking to get American racing groove vn514 wheels but not sure what would be a good combination with sizes.. as the car will be an Auto X car i want the widest possible I can fit. front and rear. I've seen a few posts saying 245/40/17's are this biggest in the front and 275/35/17 for the rear, although I've seen 275/40/18 front and 295/40/18 fit in the rear with the same rim I want. Granted I'm not sure what modifications where done to that specific IROC, so in other terms I am right where I started.... lost.
I know a little bit to know the IROC has different spacing and the wheels are staggered, but anyways need some help. TO help my car is an 85 z28 with no suspension mods YET. With an 87 GTA rear end should be the same width and spacing in the rear as i recall.
I used to have 275/40/17 all around. It was a great size. Not i have 275/40 18 up front and 305/35/18 rear. I have a 9 in wide front and 10 in rear. Im using nitto NT01s and they stick really well. The 305s just fit in the rear and don't hit anything.
This last one the car is lifted in the rear and the axle is shifted out slightly.
oh sweet! any back spacing? are you rubbing around corners? are you saying you fit these with no modifications?
minor rubbing at full lock up front. Nothing in the rear. The front bs was 5 i think. Rear was 5.75
i think 20 yrs ago i clearanced the rear around the trailing arm. Theres a piece of wheel well that is a thin piece of metal. I bent it in a little. That was for the 275s.

I ran 295/30/18 on all 4 corners. Just a little hammering in the rear if you dont want them sticking out and the front will fit but you will lose a little turning radius. Thats almost eliminated with tubular a-arms that offer better clearance on the back side, I have UMI's on the car at the time. People have ran 11" wheels and 315's but that usually requires you to clip the bottoms of the fenders.
The current build will likely have 355/30/19 on all 4 because why not, but there has been a lot of work done to the car to make that fit.
