I would go with aftermarket 17"s, all four the same width (no wider than 8"). I would buy the lightest wheel that I could afford that have the correct offset. The three lightest one piece that I am aware of are BBS RC, BBS RK, and SSR Integrals (I have these). Unless you go with an expensive Forged wheel a two or three piece will be heavier, often by ALOT. The best thing you can do is to drop unsprung weight and I'm a firm believer that there is no need to go any wider than a 225-45x17 on any z3 but the M.Hope this helps.
: My question is this: The cross spoke composite wheels on the 00 2.8 are 17X7.5 in the front and 17X8.5 in the rear. I don't like them, but I do want larger wheels than the base 16 in wheels. Hardly anyone makes wheels in this exact combination. Could I go with 4 17X8's or 4 17X8.5's or 4 17X7's or do I have to go with this exact combination of wider wheels in the rear than in the front? Obviously BMW chose this combination for a reason. Was it simply to make it more difficult to buy aftermarket wheels or was it for the handling of the car? Do I mess up the handling of the car by going with 4 17's or 4 18's all the same size?
