Advice on Bilsteings for quattros?

["James A. Desveaux" <desveaux@ucla.edu>]

Does anyone have any experience or strong or weak opinions on Bilstein HDs
(non-sport Bilsteins) for the S4/S6, or other quattros, for that matter?  I
just got a price from GPR, and the Bilsteins are less expensive than I
thought.  I've got no beef with Boge, but the aftermarket ones we can get at
reasonable prices are the same for all S4/S6 applications, while Audi used
different spring rates and valving (apparently) for different years.  That
being the case, perhaps Bilstein is a better choice??

TIA
