On our Stelvio trip 1addicts
had these sweet Performance wheels on his 135i. Whats cool is he got the Perf wheels for an e46 so they have a more aggressive offset to the wheels. fronts are 1/2 inch wider at 8"s while the rears are 8.5"s. He is running 235's in front and 255's in the rear. No rubbing either. Plus the e46 wheels were some $200 less than the 135i ones! lol
Btw... he told me that TireRack also said this combo would not work.... but they were wrong. Its an aggressive setup that works well. Looks great IMO too.
