I too find my M sport suspension on my nearly 50,000 miles E92 very
The longer I drive on highway, the more uneven road surfaces I drive on, the harder I drive, the worse it feels.
The suspension acts so dramatically over small speed bumps, wheels almost feel like off the ground for a second, even going through it slowly.
Needless to say on highway, it's like floating, bouncy bounce bounce.
When I drive hard (like a dbag going left and right), it feels like the car is throwing itself around, in a super dramatic way! Accelerate and letting go throttle, the car literally dip itself to the front, not even braking yet!!
On the back roads on the other hand (still driving very hard), doesn't feel as bad as all other situations... Only problem is it doesn't say flat at all.
According to my research (not 100% accurate) that the B12 Pro-kit is same or even better than the BMW Performance Suspension kit. I will probably end up getting this in the spring as well. Now the question is which set of sway bars?
