Heres the 315 with the car a little higher than I needed because I wanted to be sure they cleared. It was 27" in this photo https://live.staticflickr.com/65535/...6e866fd8_c.jpg _BES6507 by brendan sobers, on Flickr

and here is an older photo on the 275. I could get much lower since the tires were more narrow. same camber with both setups. -3.5~

Hiya mate. I'm curious why you decided to run a 40 section tire instead of a 35 with the 18 inch wheel?

My setup is street car biased with track attitude. Camber is -1.8, caster ended up at 6, I was running 0 Toe but I think this might have been too aggressive so I toed in a bit. I'd like to run 285 35 18 square for track use here at Laguna Seca, Sonoma, and Thunderhill. Just curious what offsets would work. +15 rear and +25 front? Maybe more?

I read on the linked wheel fitment guide that 18x10.5 or 18x11 wheels, +15 to +20 offset and some 275 or 285's all around seems to work. Not sure how much camber that is though
