After a couple of hours at Willow Springs Raceway, I have gone on the quest for a more neutral handling W124 wagon, by reducing understeer.

As with all things, suspension changes are like equations. A change ANYWHERE changes things everywhere.

Currently I'm running H&R Springs front & rear for the 300TE; Bilstein Sport dampers front; SportLine front swaybar; and the stock self-levelling in the rear.

The H&R springs are great for the track, but too low for the street IF you have aggressive spoilers (Brabus) like I do.

The Bilstein Sport dampers combined with the H&R springs in the front ride like a BMW M3, and the SportLine front swaybar reduces lean considerably.

However, with the stock rear swaybar, the balance has shifted to more understeer.

For reference, here are some swaybar measurements I have gleaned from both personal experience and other enthusiasts. All measurements are in millimeters:

300E Stock (F/R): 26.7 / 15.0 Delta: 11.7 Slight Under
300TE Stock: 22.5 / 10.0 Delta: 12.5 Understeer
SportLine: 27.5 / 17.0 Delta: 10.5 Neutral/Under
Eibach: 28.0 / 17.0 Delta: 11.0 Slight Under
500E Stock: 27.5 / 15.0 Delta: 12.5 Understeer
Delsing Motorsport: 31.75/ 22.2 Delta: 09.55 Neutral

My Wagon: 27.5 / 10.0 Delta: 17.5 Heavy Under

My goal is to get to a delta between 9.55 and 10.5, with the Sportline front swaybar.

Now if I can only find a 17-18mm rear swaybar that fits the self-levelling suspension of the 300TE/500E . . .

Hey, I got H&R springs on my W124 too. I didn't use bilstein but Koni (sports)yellow for adjustability.
Yeah, I think the H&R springs are a bit too low for street use without a front kit.

You seem to have excellent knowledge regarding W124 suspension turning. I have some suspension question and I hope really you could help me.

Do you think is possible to use a thicker spring pad at the front to raise the car a little bit ?
Do you know the OEM spring pad size ?

In your opinion, which sway bar is better for a 93 300E ?
The little thicker Eibach or the OEM Sportline ?

What sizes are your tires ? I use 17" 215/45
How you set your alignment config ?

***** The Bilstein Sport dampers combined with the H&R springs in the front ride like a BMW M3******

Forgive my ignorance , what do you meant by "ride" ? Does it handles like a M3 or the ride quality ( comfort ) is like the M3 ?
E 36 or E 26 ??

For the sway bars, try contact Randy in http://www.epsparts.com
They sell bars for Mercedes, they might be able to help.


Thank you very much for your time. Your help will be greatly appreciated.
