Regarding damping rates and mass

From what I gather there are basically two applicable types of shocks from Bilstein; HD and Sport. Now I've seen these noted for various BMWs and Porsches. But this seems to be inherently problematic.

I assume everyone is trying for a "critical damped" system. This calculation is dependent of mass. So if a shock with damping "X" works perfectly with a front engine BMW with say 2000lbs over the front wheels, then it would be way overdamped for a 911 with 1200lbs.

Furthermore, for a 911 it would seem a higher damped shock would be required for the rear and a lower damped shock for the front. Otherwise, you'll induce a fore/aft pitch mode to the vehicle.

Question: Can the shocks be ordered with various damping coefficients?
