Lloyd,
bpdA is not complaining about the bottoming problem that seems to plague the '05's. Shocks do have a strong influence on the ride quality. Try driving without shocks, you'll see.

bpdA,
It sounds like the at least one of the shocks may be bad out of the box. Did you go from the OEM shocks to the Bilsteins or did you have something else on there? What part numbers did you get?
