Already running a set of single adjust AST dampers. Still using the factory Nismo springs though.

Gotcha.

I may try and run 285 square, wheels I want don't have that offset and I don't want to run spacers since my other wheels for perfect. 295 up front would be nice though!

They can fit on a 9 9.5 or 10

Z2s don't come in a 285 19 atm. I am hoping the make one.

And this is why many of us with dedicated track/autox wheels go with 18's. Better selection, better prices, and lighter weight.

Looking at the ZII's I could run a 285/30 square, with the rivals I would be running a 275/35 F 295/35 R stagger. Will I run into any issues running a 30 sidewall all around? I will be taking these to Hallet raceway for their HST events too. Hallet is the closet circuit track to me.

You could. That's like 2" smaller than OEM. You lowered already? I don't know for autox but you want some sidewall flex for bumps and stuff or your body and wheels are going to get beat.

Stock height right now

fwiw the next set of A6's I get will be 295/30's. Unless of course Hoosier decides to start making 295/35-18's.

The G Force Rivals are looking like my new tire, 275/35/18 F and 295/35/18 rear. I would like something with a 40 sidewall but would rather not sacrifice width since the narrow sizes seen to all have the higher sidewall. Will need a good summer/winter (just cold weather) tire for my DD set next but that's another thread!

Buy my Hoosier a6 with tsw nurburgring on it. I can't use it because I am no longer autoxing

I want to run street tires for at least another season before I step up to slicks.

But the purple crack is so much more fun.

I want to go 18s but i am unable to find a light set that is within 7mm of stock offset and will clear the akebonos.
