i have speedline superturismo's at 55mm offset..can't do subaru 4pots...i can get plenty of clamping force from upgrades to the stock system..i just wanted a little more wheel filler and more surface area to disipate the heat generated by my fun days on backroads. Plus i want to keep costs relatively low, have to buy new toyo t1-s's now also...Thanks for the input though guys!
