Test fitting for 18x11-315/30 combo
Since the install of the TCI Engineering suspension, I have room for for a wider wheel/tire combo. The popular consensus for ultimate autocrossing is 18x11 wheels with 315/30/18 tires. The biggest hurdle is figuring out backspacing. I have plenty of room up front(at least with no inner fenders), but in the back is the tricky part. The stepsides have a slightly more narrow fender lip to fender lip measurement than fleetsides. Then, there's the issue of the shock placement limiting how deep the backspacing can go.
The final numbers are 6.75" backspacing or roughly a +20 offset. I can actually use this on all four corners and rotate them.

I have nothing useful to add but I want to say that looks super badass with those massive tires up front and behind.
