I run 325 square pirelli scrubs on 18x11, no issues with that. Not sure if 18x12 with 335 will rub in the back, but your fronts should be no issue(after the strut grind). I got my scrubs from a friend but I think the other option is to go to usedracing tires.com

Oh you might not need strut grind with the staggered setup, just the square set. If Apex says you don't need it you should be good(although I don't think apex recommends any 325 sizes up front). I would take a peek under and see if the tire is close to rubbing on the strut. That would be a massive failure on track if the tire rubs during lateral loads. I'm running the 26mm spacers up front for my setup. I had to grind my struts a lot.

Ok ZLE may not require grind
I probaly stay 305 either 315 front
Apex recommend 315- 30 335 -30-18
Picking up used set of NT01s 305 35 335 30 18 from my buddy. Hopefully work out well
Thanks for advice ��
