I recently had the Eibach Pro kit springs installed on my 1991 300 SEL (W126). It made the car look great, but ride was really sloppy. The car had the Bilstein comforts originally when the springs were installed. Since the shocks were new, I had left them on. Had Bilstein HDs installed on all four and it still is bouncy. If you push down, the car bounces three or four times after the initial full return before stopping. If you pulse the brakes at a stop, you can see the whole car bounce a couple of inches before settling.

The shop I use pointed out the problem right away and felt the springs were not tempered or the wrong ones. I spoke to both Eibach and Tire Rack who blame the shocks. I have comfirmed all the part numbers to be the correct springs and shocks. After spending $2K on this, I am about worn out.

Any ideas???
