18x9 30 offset front and 18x10 25 offset rear. I've used a 5mm spacer in the rear recently with the 25 offset so some room still exits to the outside. I think it's possible to have a square setup. 30 ET with 18x9 and 255's on all four corners. The 255's will fit the front IF you roll the fenders. The Stoptechs are 355x32 rotors, ST-40 Calipers (4 piston). Plenty of room with the Forgestars but the stock wheels require 5mm spacers to clear the calipers.
