nilfinite · 07-17-2013, 11:28 AM

Been noticing when I drive on a certain stretch of freeway (I-280 near the Mariposa exit), that my F30 with M Sport suspension has been really "bouncy". The road has a smooth wavy pattern (shallow dips). My previous car, Infiniti G37S, would be slightly bouncy there as well but would smooth out above a certain speed.

Want to figure out if upgrading to the M Performance Suspension would fix that. The G37 had the optional sport package with stiffer springs and it seems like the Infiniti was stiffer than the BMW. Not exactly sure.
