You wont clear in the rear with 275's if you are stock. I have the
eibach pro kit with 245/45/17's all around. The tail pipes(2.5") barely clear the back of the tire, I have about a 1/4 inch left of space. My car is a notch though. You might have to move the pipes in more, dump the quads or get adjustable lowers. Thats my car though, other people could share their setup with a hatchback....
