yes, in my quest to find a so called good price for a OE front strut replacement
on my sport wagon...Stay the hell away from Schmeidmann... Santaclause. That said, Sachs spec'd me with those Advantage 556-838 ft. strut replacements for my 2002 (S227A) suspension...in writing. Bought those: wrong! The were awfully harsh, the wrong strut insert. The SACHS Advantage 556-636 work fine in my car now. There used to be much confusion of this much to my dismay and wallet. Those red label SACHS advantage inserts you mention above and that I used are for the E39 sedan with sport suspension (not the 2003 E39 sedan with the M5 parts). Dare I say ask SACHS? I'd say ask as you are doing here in the forums and maybe give these KONI's a try on lowest settings and creep into how you like them set after a few miles I've used KONI's for 35 years and have been able to dial them in to happily meet my 'custom' needs on several non-BMW applications.
