that's a very hard question to answer as it all depends on the wheel diameter, wheel width, wheel offset, wheel backspacing, and suspension mods if any were made to lower the car. whether or not you keep the outboard shocks on the rear also affect the the max size combo you can run on the rear too. generally, you can get by with wider combos in the rears since you don't have to worry about steering clearances like you do on the front end. best advice I have is to go talk to the guys at the nearest and best high performance tire shop, they will be able to give you some ideas of what will and won't fit.
