It is really something else. I understood damping technology to an extent but I didn't actually understand it until I got the JRZs.

Thanks man. JRZ says this:
Unlike many other single adjustable suspensions, damping balance is carefully maintained between compression and rebound.

You mean like a washboard surface? I did a 2-hr cruise yesterday on the highway and went over a surface like that. With the stock 335i springs/dampers I could feel the car moving up and down sort of like a trampoline. With the JRZs ... felt nothing at all. If I didn't drive over that road before I wouldn't have known it was a washboard surface (aside from seeing other cars bouncing up and down ). I could not wipe the smile off my face afterwards.
