I'm not sure if it will correct the problem completely but I hope for significant improvement. I've changed the subframe bushes for 70d AKG polybushes and might go for a different suspension setup. I'm running a custom bilstein and eibach setup with e92 m3 rear sway and e93 m3 front sway bar (thicker).
Does this rear end feeling came with installation of M3 diff?
BTW is AKG bushes something similar to powerflex? Did it improved your ride?
