No, no, hmm-possibly, and no way. The struts are exact replacement "standard" Bilsteins. I have already considered the possibility of new struts (replaced 6 weeks ago) not "settling in" although mechs swore that's impossible. I have not considered a possibilty that the original were Sachs. i'll check. Incidentally, I saw a 1985 190E blow by me yesterday. Quite obviously had 4 new shocks, because he was as high as me front AND rear.
I wonder if there is an adjustment of some sorts regulating the vehicle height. I know nobody mentioned it, but...
