dont cut off too much too soon because the car will drop like a stone. I'd say give it a go with 1-2 coils at first. then see how everything settles in place

Cutting coil springs in any car is a bad idea let alone a safety issue.

You'll be much better served springing for a real set of lowered springs such as MB sportlines, H&R, Eibach, etc.

Not entirely true although for conventional mcpherson design it is a different story. Cutting springs on a W124 is perfectly fine, just take it easy.
As bsmuwk said, go with about 2 coils and see how you like it.

At full extension with the strut removed, the spring still won't pop out. So cut with the strut installed, no fear for safety :thumbsup:

There's a right way to cut a spring and there is a wrong way to cut a spring. It will ultimately be unsafe if you've cut the spring the wrong way because you're changing spring dynamics. Mercedes have springs with tangential and square based springs. The only SAFE way to cut a MB spring is to cut the tangential end (the end that cannot stand the spring upright is the tangential end). If you cut the square based end, then you've just opened the Pandora's box of safety hazards. If you cut the tangential end, then you haven't changed the spring dynamics as long as you follow the tangent.


See how that works?


It WILL be unsafe if done incorrectly.
Safe if done correctly.


The only benefit to lowering springs is that their spring rates are much firmer than stock springs thereby helping resist bottoming out.

That's a good point! Almost forgot about that.

If you'd like to go a lot lower than the factory struts can handle, Bilstein Sport struts have shorter rod travel to allow for a lower car :D

Do you mean installing (Cut) R129 springs on a W124?

I didn't know those springs were interchangeable between the two models. But, based on the responses it is. Can anyone confirm this? and if so, can you use an R129 front strut on a W124?

Holy cow, 2 coils! I'd start a lot more conservative than that, especially since you're working with R129 coils. Take a look at the 124 and 129 coils side by side and see how much they differ, and then go from there. I cut 4" from mine and it made a nice height difference. I think that translates to about 1/3 of a coil.

Yes, you can run an R129 front strut on a W124. They're the same.

The R129, W124, W210, W202, and W201 can interchange springs - however, springs rates vary.

bsmuwk, thanks for the info. You just saved me a couple hundred dollars. I upgraded my sl's struts and the original struts are still in good condition. I'll install it to my e320 to replace its sagging struts.

How about the rear shock, is it also interchangeable?

I went at it last night :D
installed front camber plates rear camber arms and started off cutting 2 coil's off all 4 corners will post pics later today , think i will cut another 1/2 coil from the rear :D

mind you my car is sitting on 18x8 front 18x9.5 rear 225/40-18 on all 4 she looks dam good , as a side note i need new struts on all corners lol

and i used a 4" angle grinder with cutting wheel to make the cuts just FYI

oops! I was not able to correlate aggressive with the feel of the ride. I was thinking more like, if the ride became harsh, hard or bouncy. In this case, aggressive appears mean hard. No?

when i wrote aggressive.... it was more of a joking way of saying Very firm or hard the car now handles like its on rail with very little body roll

also another thing i have notice when i pull in to steep angle driveways at an angle as not to scrap , i can hear the creaking as the chassis twist

r129 springs in an m104 w124 , is not for the faint at heart it is stiff

Sorry to brin this from the dead.
I was doing a search and this came up. so the springs from the 190e and the r129 sl fit and the r129 sl shocks fit. do the 190e shock interchange as well as these cars all have a 5 multi link suspension system.

Looking to lower and loose my wheel gap but at the same time have a much stable handling w124.

are and of the springs from other chassis cars shorter or longer for ex w201 or w202 or r129?
Was thinking of getting w201 hand r spring for the 2.6 for my w124 2.3 and go with bilstien performance shocks from the r129 300sl?

Any ideas?
