Bilstein HDs=AMG sport shocks, about 25% stiffer than the non sport springs. Slightly tighter ride and improved handling. I have the Bilstein Sport shocks, which are for vehicles with lowering springs, H&R in my case. I had bilsteins in my last vehicle as well, and loved them. They hold up very well.
