Hi

I noticed my X5 is a bit jumpy, specially the rear which is equipped with Air Spring.

I was doing 100km/h on the highway, over some pot holes and i could feel the rear jump to the side abit, not enough for me to counter steer, nothing like that but you get the picture.

So i start to wonder, how is this Airspring compare to proper progressive coil spring? Can it obsorb the road condition as fast as the coil spring?

I've raced on many tracks in Aust like Phillip Island, Sandown, Winton ..... etc, have no problem control a car at highspeed but this car is meant to be for the Wife to drive so i'm a bit worry.
