I have Bilstein HDs on my UrS4 and they only have
one mounting perch.

Default You are talking about the rear shocks. Bilsteins used to (in the "old" days) come with....

three grooves machined into the rear shock shell. A middle "normal" position plus one about 1 cm higher and one about 1 cm lower. The last set I bought (for the S-car) had no extra grooves. Eibach provided a special spring perch to modify the rear spring perch height. Otherwise, a groove could potentially be machined into the shock shell (by someone who knows what they are doing).

Default can we use aftermarket springs with the hd's or is that asking for trouble?

I think I have hd's, but not real sure any way of knowing for sure, car sits kinda high, and yes they are bilsteins.

Default We just went through this before Christmas. HD are for the stock height springs, Sports are..

shorter and are meant for the shorter lowering (H&R, Eibach, Intrax, etc) springs. You can run the Sports (with some success) with the taller OEM springs but running the taller HDs with the shorter springs has a high risk of failure, i.e. the suspension bottoming out on (actually in) the HD shock. (Kaboom, Ouch). This is why Bilstein made the Sports shock.

If you want to risk US$400 to see if I am wrong, please feel free to ignore this advice.
