18" wheel fitment for '69 Camaro

[alistair]

Hi guys

I've done a little looking into this and I know the answer really is "depends" rather than anything concrete but I'd like to sap up as much of your excellent experience as I can for our project '69 Camaro

The car is currently dead stock and was restored a couple years ago.

We want to run about 2" lower (not with blocks) and we want to run 18" diameter rims. I'd love to think we can get 10x18 under the stock rear tubs with stock located springs in place. I somehow suspect we can't though.

We will be running disc brakes all round and I am aware sometimes that changes the requirement on backspace etc. a little.

Your thoughts and comments are most welcome guys.

I am running 245/40/18 and 275/40/18 on 18x8/18x9.5. The approximate fender lip to ground measurements are 24.5f and 25.2r. Fronts rub when turning in parking lots a little. I've pushed it pretty hard on a twisty road with no contact issues. Rear tail pipe routing may be an issue, my 2,5" pipes needed to be flatted aproximately .75". Pan head bolts and a little metal massaging should neutralize it. Stock A-arms, lowered coils and leafs, 1" blocks in leafs. Pinion angle went downward 2*.

thanks, that's really helpful information. What backspace have your wheels?

You can run 18x10's w/ 275-40-18's on the back if you roll your lips on the 1/4's and you don't have your ride height super low. I did and had no rubbing issues with the suspension setup right. This was with de-arched dropped leafs and QA1 shocks.

The wheels were 18x10 with 5.75" BS, stock width rear and Baer disc brake kit.
