Bilteins HDs/stock springs(BTDT, type44)

[Konstantin Bogach]

Hi listers.
I installed HDs on my 200tqa a year ago.  I like that stiff ride.  But
every bump makes me doubt my decision.  One of this bumps, pretty big
one, accelerated door look failure.  But I thought that this comes in
the package with better handling... until I drove S4 with Bilsteins
Sport/H&R springs.  This setup is stiffer that mine but I feel that
suspension is working on the bumps damping shocks.  My car, when the
height of the bumps/potholes exceeds approximately 3/4 -1 inch,  feels
like there is no shock damping.
Can it be that shocks' valving require certain stiffness and my current
setup is not compatible?  Anyone  happy this such setup?

Konstantin.
