I'm running -3* camber up front with 8.5" width wheel ET+30 and 245 NT05's, and it's already rubbing the fender liner. I
think 255's might fit with -3* or more of camber, but it also depends on wheel sizing/offset.
As for my rears, I'm running -2.2* camber with 10.5" width wheel ET+22 and 275 NT05's, and the rear passenger side rubs the fender lining @ Laguna turn 6 every single time. My rear fenders are rolled and ever so slightly flared too
