I'm definitely leaning toward 19". Just out of curiosity, is anyone aware of any quantified difference in acceleration (or other quantifiable differences in performance) between either the E46 or E92 M3's with 18" vs. 19" wheels? It is quite understandable that with all other factors being equal, the 18's would be better in certain respects, but how much better (would it be 0.1 to 0.2 seconds for 0-60 or quarter-mile? More or less?) If the 19" forged for the E92 are the same weight as the cast 18's, it would seem (based on the comments above) that any acceleration advantage of the 18's would be very slight... Thanks.
