Hello All,

I am starting to research refreshing the suspension on my W124.

A couple of notes to frame my needs.
-Not building a race vehicle.
-Wheels and tires will be upsized, but not looking for advice in this area as it is already sorted.
-Will be moderately lowering vehicle approximately 1.25-1.5.".
-Primary goal is high speed stability with some compromise in road thump acceptable.

Looking at polyurethane bushes and correcting camber / toe back to stock at new ride height and looking for suggestions for which parts to purchase and where.

Thanks in advance.

I would go with all stock replacement bushings where needed over polly. Better ride quality and longer life. As you lower the car you will get camber and toe in in the rear unless you get adjustable links.

Its worth replacing some of the 124's soft and high riding qualities, if you aren't just driving the kids to school or something mundane.
1) Watchout the tires don't rub in the front.

2) You might want to look at using Koni gasadjust shocks too, to set to whatever spring rate you end up with.

I used OE Sportline suspension parts on my '87 300D and it handles great now, no body roll in corners and very responsive. I had adjustable camber links in the rears and had to replace the first set as they started getting worn and clunky. I forget what I used to replace them with but I had a shop that does race cars and high end vehicles adjust the suspension. You might not have good results with alignments after you mod the suspension because places like Firestone and (I daresay) even the dealer will have problems getting it right.
And I second the anti-poly recommendation.
so, you might wonder why I don't recommend Polyurethane bushings? because the '99 E300D I bought from another Forum member turned out to have Poly bushings and the squeaking noise it made over every bump in the road drove me nut!
I replaced a couple of Poly's in the front but its still got some in there and squeaks on turns.
I should just shotgun the whole car back to OE rubber.

Thanks for the feedback.

I leaning towards OEM, but with adjustable camber.

Any suggestions for camber and toe adjustment in the rear of my 124?

I've a 95 w124 with Sportline bits, though I replaced the MB shocks with much preferable Konis. The other car has some familiar aftermarket springs, drawing a blank on the name, that lowered it about an inch, and heavy duty Bilsteins, as well as stiffer roll bars. These pieces are all a bit more robust than Sportline, with corresponding ride effects; didn't need to go to adjustable camber for this mild drop and would not want it lower with the condition of roads generally. I've some old, never-installed camber rods if you're interested.

I've never met an adjustable rear camber link that I liked. The factory link is somewhat banana shaped and every adj. link I've seen is straight. When I ran sportline springs in my 91 coupe, it was just over 2 degrees of rear camber. I decided to lengthen a pair of stock upper camber links to keep the basic shape. I drew the spindle mounting points to scale on a piece of spare sheetrock and calculated that 5mm extra length should correct 1 degree of camber. My math was pretty close and ended up just barely under 1 degree camber, which was my target.
