300D 2.5 W124 sits low after new spring install
 

I had two broken front springs that I just replaced. The springs were rusted and we couldnt see what part numbers were actually on them. We ordered the springs from the dealer and they ran the vin, and came up with:

124-321-21-04 "lightweight" spring

201-321-11-84 - the thickest shim pad you can get (18mm)

The problem im having now, is it seems like the front end sags. When there is people in the car, its much worse.

I took measurements of it today, sitting flat in my garage, with a half tank of diesel. Middle of the center caps to the lowest part of the fender lip:

in inches

Front Left: 14 3/16
Front Right: 14 4/16
Rear Left: 14 14/16
Rear Right:14 10/16

I know there is another spring that is made for this car, the 124-321-21-04. This is the "stronger" of the two springs, and I think the dealer made a mistake, and I should have this one. For what its worth, my car has ASD, pass airbag, sunroof, alarm, etc.

Ive attached 4 pics. Any opinions are greatly appreciated.
