Once and for all does mercedes make a 4 bump rubber spring pad for the rear? My dealer says he only shows 1,2,3 bump for the rear.

Do they make a 201-325-12-44 (23mm)

I have lowered my car with lowering springs and need the back just a touch higher to match the front. I have 4 bump in the front and 3 bump in the rear now.

And they would be right Richard. I checked my 124 CD and it indicated that also. Four different thicknesses for the front and three for the rear. Perhaps reducing the front pad thickness will help. That is about your only alternative.

If I may ask, what brand of springs did you use? I lowered (AMG) my '89 300E without any trouble. The rear sits approx 1/4" higher than the front.
