Would ZR1 with 275s front fit without rubbing with spacers? If so what spacers I need?

As for the back I have a 4th gen rear. Would 315s fit?

 

2" and 2.25" spacers (I had both sizes, now using just the 2") on my front with ZR1's (both available offsets) rub on my car.
315's usually require a hammer and fender rolling.

 

honeslty, do a search - this has been covered a bunch of times, and i know for a fact that there is great thread that i posted a bunch of great info in...

 

I searched "315 tire" and dint get anything.

 

Moving to the correct forum per the sticky at the top of this forum..

 

I have 315's in back on a 4th gen rear end and everything fits fine, no hammer needed.

 

that's because the 4th gen rear makes up for the offset difference.

 

What springs are you using? Ride height plays a big role into clearance and rubbing. The condition of the struts/shocks is also important, you want to avoid excessive suspension travel.

 

ok... now that i have more time... I did a search and came up with the following info in adidition to what already i have experianced.

a) you having a camaro makes a huge difference. Firebirds between the sheetmetal are 2" total narrower in the body - which make tucking the wheels in even more difficult in the back.

b) The fourthgen rear comes 2" wider per side - this could be a potential problem. Make sure you get at least the 50mm offset 17x11's... the 36's will stick out.

c) I don't think you'll have to do much clearencing, but if ya do, all it takes is a 2 1/2 lbs sledge, and some por 15 to paint the well.

d) front is easy as pie - 2 - 2 1/4" adaptor up front... I do get some rubbing when i go to lock, i would have been better off with the 2 1/4" spacers - they still would tuck under the fender fine.

Basically, 17x11's can be done no problem, but for you, because you have a wider rear, you are going to possibly need a custom offset wheel to get the best "tuck" possible... there is nothing worse than a set of wheels sicking out

 

Why?

 

- my 91z was exactly the same as my GTA. Even had the GTA wheels on the Z for a while, zero difference in offset or fender clearance.
- I'm currently running 17x11 with a 8" bs, 4th gen rear, 315/35/17's on the back. Sits square with the wheel well. Do a search under my name, there's plenty of pics floating around.
