I think the HM2's are the best looking wheels around. My M3 is Arctic silver so I really want some (I think those look best on a silver M). But do you feel the 18's detracted from the M's handling and/or acceleration? I had a CRX before the M3 and everyone said 16's would detract from the handling. I bought them anyway and could never tell any difference. But I would hate to spend Hamman $$ and feel like my handling suffered. BTW, Do you have H&R sport springs?
