If your shocks are more worn in back than front that will allow it to settle in. If your shocks are worn I would put on some new bilsteins and see what that looks like first.

Chasing ride height issues is tricky. As an example, Brian Carlteon spent a lot of money and effort trying to get his car just right including all sorts of bushings and finally bought custom springs and I am not sure ever got it just how he wanted it and he is a very accomplished person mechanically. It was initially too low and in the end was a bit too high.

I've had about thirty benzes through the years and have had only one spring that was weak, in a 115. I put an inexpensive spacer in to level it and drove on. Other than that I have never replaced a spring and have never replaced the diff mounts and most of my benzes have been fairly high mileage older ones.

I have had some cars that were higher in back, some higher in front, and really I have never been able to tell from handling and ride any significant difference in performance.
