Let me set you straight on this.
Bilstein Comforts are much the same as OEM ( length, damping, etc.).
Bilstein HD and Sport have the same valving, with the Sport's being shorter, to compensate for lowering springs.
Bilstein recommends the Sports on vehicles that are lowered 30 mm or more.
Having a combination of Eibach springs & the Sport shocks, I find the combination of ride & handling just about perfect.
I do NOT like a stiff ride, but not a " Floater " either.
