What's your ideal 18" tire size for track use? - Page 3

I've just found another interesting option:
Nitto NT01 275/35/18 for $240 delivered. What do you guys think? square setup of 10"X4

I'm looking into an 18" Square setup, and keep seeing that a 10" wheel with 25mm offset with 5mm spacer up front works. I just wanted to verify: Is this true for a regular 1SS with MRC, with everything else stock (NO camber plates, no other mods)???

(I was already leaning towards running the Hankook RS4 in a 285/35R18, this thread has helped cement that idea).

I'm currently running GM Recommended "Track" alignment, but may see if someone can squeak out a tiny bit more camber. Is it safe to assume that wheel size won't interfere with camber adjustments?

Can't answer the regular vs. SS 1LE MRC's. Can't imagine there is any major clearance differences. Good call on the 285 RS4's.

I already have my 305/30 19" RS4's, just waiting on my 19x 10.5 et22 Apex wheels to arrive.

I think that's not enough tire.

Provoste is running 18x10 +25 w/ 5mm spacer see picture above.

I'm running 18x10.5 +22 w/ 12mm spacer and have a few mm clearance to the shock tower (no grinding and max front camber).

^ Are you guys running longer studs with the spacers?

Yes.

Anyone able to fit a square set of 18x10 or 19x10 with tires mounted into their cars for swapping trackside? I imagine it's impossible with our trunk openings.

Yep. Last season once I loaded all 4 18 x 10 wheels w/ 285/645 PZero slicks in my car along with a jack and tools. I believe I had one wheel/tire 1/2 in the trunk, 1/2 on the pass through, then 3 loaded in the back seat (folded down). The 285 width 18" was able to be loaded through the trunk.

IS THERE ANY 18INCH set up that does not require spacers ?

Depends on what your goals are. If you want a square setup and also want to go as wide as possible, I think you are going to need spacers. The compromise would be either spacers in the front or a lot of poke in the rear.

18x10 you need at least a +20 offset in the front to clear the shock.
18x10.5 you need at least a +10 offset in the front to clear.

Both of those setups would have a decent amount of poke if run in the rear.

If you don't care about a square setup or maximizing width then you can easily get an 18" setup that doesn't require spacers.
