On a somewhat related subject I recently ordered Bilsteins for my 400E. When they arrived the fronts were heavy duty and the rears were comfort. I called the supplier to report the shipping error and was told that that is what "Mercedes" is now recommending on the V8 124s. The Bilstein website said nothing about it but the Bilstein website is something of an embarassment to begin with. So I put em on. Shipping error or not I'm quite pleased with the result.
