I am running 18x8.5 with 245/40s in the front and 10x18 with 275/35s in the rear (PS2s). I'm not sure of the offsets but the wheels were custom made by CCW with the right offset so I wouldn't need spacers. I just told them that I was running stock 7.5s and 9s with 7mm and 15mm spacers and I wanted roughly the same stance with no rubbbing and no need to roll the fenders. Those guys really know their stuff.
