S4/S6 Eibach springs on a 200?

[Peter Schulz]

Dave:

This thread comes up occasionally.

HDs are optimized for factory springs (longer body)
Sports have the same valving but are shorter for lowering springs.

The Bilstein techs explained the following to me:
When using HDs with lowered springs you are effectively using too long a shock and the piston placement is not optimal ( you have affected the normal piston travel) , potentially damaging the piston and or seals...same thing when using Sports with factory springs.

call Bilstein Tech support to verify.

My recommendation is that if you really want to use the lowering springs, buy the correct length strut/shock for the application and sell the HDs.
