i have an 07 with the 3.0 and 20s. i second the alignment comments. ran my set of dunlop runflats and didnt realize the rear had so much negative camber. corded the inside edge. switched to conti dws and aligned it. no deterioration in handling really and tires arent getting hammered. the rear negative camber was like 2.5 i think which is more than my m3 set up for the track.
