    Default Squared set up (18s)

    So im torn on what to do for wheels next year. Im almost positive I want to run a squared setup to be able to rotate and have a wheel that will be able to go on any corner for a spare. They also have to clear Brembos on all 4 corners. Sounds like the TSW Rings in 18 by 9.5 with a 40 offset are about the best and only choice to do this. But seems everyone has a different answer on whether or not Ill have to roll my rear fenders or not. I really dont want to roll my fenders with our crappy paint. Ill have Eibachs with Konis for my suspension setup. For those of you that run this setup with 275 all around how is the DD aspect? Am I gonna be fighting my steering wheel all the time with 275s on front? Im trying to get away from having to run the spacers with my factory 18s and 19s to clear the brembos. I use the factory 18s for my track setup which im trying to sell. Any help from the guys that know this setup would be nice.

    You won't have to fight the steering wheel. With my 275mm tires on the front I didn't really get any tramlining.

    You will probably have to roll your rear fenders. I rubbed with 285mm wide tires at stock height with a little weight in the rear of the car. Same width and offset specs on my 20" rims (9.5" wide at +40et).
