If I drive over a speed bump, it feels like it's gonna bottom out in the rear. I really don't want to screw up the "BMW ride" I paid for, but the car feels a little scary on undulating roads. I call it "porpoising" for want of a better word. It rocks back and forth like a rocking chair. What do I need to do to fix this, without reinventing the entire suspension?
In this case, a set of quality dampers are mandatory. If you do nothing else, this move will improve your handling and ride tremendously. The stock dampers are crap. Try Koni Sports, Koni FSD's, or Bilstien HD's.
