Yes, that is exactly what happens, but it's in a rather speciallized
condition. The shocks are over damped for high frequency oscillations
such as ridged pavement where the ridges are perpendicular to the roadway.
In all other situations, they are really an ideal match.

A slightly stiffer spring may be able to get rid of the high frequency
issue without too severely affecting the overall ride, WHILE getting a bit
body control. Too bad custom spring rates aren't as cheap as custom shock
valving, at least for Bilsteins.
