Part 1 of 2:

Over the years, I've tried to post what I have on 200q20v springs & dampers, but recently, the mail list limits the size of the post to less than my writeup's size.  So, I'll post this info in two emails.

I happen to like the 200 being lowered about an inch, which is something that H&R as well as Eibach desgined into their springs for this application.  The disadvantage of lowering has been driveways and speed bumps, as my Sebro exhaust sometimes gets scuffed a bit.  There have been many posts about using spacers to bring the ride height back up again using the springs I've listed.  Perhaps, some lister can provide the part numbers & sources for those spacers, as I don't have that info

But, the best handling IMO was from the H&R/Koni setup.  However, this arrangement is harsh and caused a resonating, vibrating ride with 70 mph freeway driving.  With an hour commute to and from work each day, after a half-year or so, I jettisoned the setup.

Eventually, I settled on Eibach/Bilstein as the best compromise for me & how I drive the car.


Here's the first half of the writeup:
