I am also running a 255/35 Front, 295/30 rear with Michelin Pilot Super Sports, and one of my biggest comments on the car is how 'fat' the rear looks with so much rubber back there. And it does look good.
Dropped on K&W v3's (1" all around) and no rubbing. Wheels are +22 offset all around with a 5mm spacer in the rear. Looking to go for a 10mm spacer when there's extra cash laying around. Also looking to go wider in the front. I'd like to fit a 275 up front, but I'll prolly be stuck with 265 just to prevent rubbing until I can get some front camber arms.
