What would be a good offset for 18x9 235/40? I'm MAY be interested in doing some rolling for the rears. Neuspeed race springs/koni yellows with natural camber. Roughly 2.75" front and I think 2" rear. I'm on some heavy ass 19's that I need to take off.. I'm looking at these bad boys. I was thinking 18x9 +35 235/40 but I'm worried I'll rub. I would love to fit this without adding more camber and fiddling with the finders if possible.
