67 Camaro ,Biggest wheel size 18" HELP!!!

[huggero]

Ok im very confused, Ive heard 10 diff things from 20 diff people. I have a 67 camaro with a moser 12 bolt and a hotchkis TVS rear suspension, QA1 shocks mounted in the stock location. My lip is not rolled because the car is painted. I want to run a 18X9 Budnik wheel in the rear. What is the biggest tire I can run in the back and not create any rubbing and still clear the wheel well? I am also using A wilwood rear disk brake kit. Any suggestions would be greatly appreciated. Thank you.

If all that you are looking for is tire size, you can safely run a 275/40/18 with a 9" rim provided you have the proper backspacing (5.25 or 5.5).

So it would be safe to assume that the 5.25 backspace would be the safer route so it doesnt rub? And also I see alot of people running 17" wheels instead of 18". Will the 18 " wheels not clear the wheel well as good as the 17" Im just curios. Im going to spend alot of money on the Budniks and I want to get it right. Thanks

18" will give you more clearance around the lower shock mounts, as well as more clearance around brake calipers/rotors.

275 wide tires shouldn't rub.
