[s-cars] Shock Faux Pas?

[John Farr]

Wisemen of Listdom,
Brought the S4 home from the very trusted, but non-performance  
oriented shop today with new rear Bilsteins replacing the  
embarrassingly shot OE units, thinking I was taking the first step  
down the slippery slope. Was told they would work with slightly lower  
Eibachs for the next step later. I wanted it stiff, and it is really  
stiff ! I'll live with that, but, I swear, the back end is lifted.  
Could the incorrect shock change the ride height? Whatever damping is  
there is minimal. What is the correct part # for stock or slightly  
less than stock ride height Bilsteins? After hours of looking at  
suspension web sites, I've only confused myself further. Did our cars  
come with some kind of sport suspension option, or are they just  
talking about aftermarket fitments?
I've been hanging around this list almost since the beginning, and I  
should know the answers.
Yours Stupidly,
John
