Guys, I just bought a TT and looking to get some new shoe. I want to run at least 275/35/18 in the rear with the car drop. What is the widest wheel i can run in the back and what offset is safe without rubbing?

 

Start here.. the wheel offset calculator will let you play around with widths, offsets, and spacers. 9-inch rims are the widest I have seen used, but there may be wider ones out there. I run 18x8.5 ET37 with 25mm spacers on mine.

 

Are you rubbing on the inside, is that why you use the 25mm spacer for?

 

I needed the 25's on the front to clear my Brembo's with the wheel offset that I have, I just made the rears the same to keep it looking right. My rims are right at the edge of the fender, I get a minor rub when I corner hard at the track, but for daily driving, no problem.

 

Do you have stock suspension?

 

No, I've got a Koni Sport coilover kit and I am lowered about 2 inches from stock. I added a full K-mac kit to the rear to get the camber back into spec.
