I probably would have asked that question before I bought the dampers.

Here is what I found in the Sachs catalog for a 1996 C280 202.028:


SACHS170 450

• Labour [h] : 0,80

SACHS102 515

I checked in the online Bilstein catalog but it doesn't tell me anything about the differences between a B4/B6/B8 so I can't say what is equivalent to what.
