I've been looking for Bilstein HD's for my avant, I'm gonna be matching them with Euro Sport spring. I've checked Shox.com and I think there the sport model.

the part numbers I have are:

front: F4-P36-0370-H0
Rear: F4-B46-2066-H0

Thanks

...part numbers under the applications with "stock" springs. IIRC, Bilstein specs their Sport model for anything but "stock" springs.

Another IIRC - the Euro sport springs for these cars is essentially the same as the 92-spec springs. This is all from memory, so if I'm wrong there will certainly be a gleeful correction. ;)

[edit] As to where - I got strut inserts for my 100S Avant from autohausaz. I looked at SJM Autotechnik too, and they had them. These were Sachs Advantage, but I was looking at Bilstein at the same time. ISTR both of those guys selling Bilstein HDs for our cars.
