At around 3,400 lbs and 420 hp, that's a weight to power of 8.1 (just based on base car pre options). Pretty high weight to power and higher than M3 GTS...if those are the stats, it's not going to be a huge improvement in straight line, but the light weight will be nice for handling/dynamics. There's also modding potential, but isn't any increase in boost an auto void on warranty (unlike N/A tunes??). Nice work..

This would represent an approximate 300 pound weight reduction; great news for BMW enthusiasts who bemoan the increasing weight of cars in general. The caveat to keep in mind however, is that curb weight is calculated based on the total weight of a vehicle with standard equipment, and with the ever growing list of standard equipment and technology in late model cars, don't be surprised or disappointed if you don't see exactly 300 pounds shaved. What's important is that the E46 M3 weight is being used as a target, which in any scenario, should result in significant weight reduction for the new M3 and M4.
