MB Sportline springs for W124

[gooldie]

Just had my w124 320 estate in for a check up and was told that 3 of the springs were broken was wondering if it was worth changeing them for the sportline one where would i be able to buy them from or source part number for them? Has anyone else done this and is it worth doing?

Just done a google search and came up with this

Would these part number appear correct if so would you go for heavy or light rear springs? would i require any spring pads/shims?

To get the correct balance for the new springs you will need the matching sportline struts - an expensive excercise for little benefit.

I would stay with standard replacemment springs all round.

Well i am planning to fit some 17" wheels so want to lower the gap between the arch and tyre so that it looks right.

Put the 17s first and take from there.

Nick Froome will be the one to answer this thread. He is Mr W124 Estate in the UK

well got the wheels fitted on Friday thought i would post up some pictures

love the wheels but the car looks to be sitting very high especially at the front have picked up a set sportline springs but am worried they are not going to lower the front enough any idea how much lower they are from standard and should i chane the spring pads and if so to which ones?

 

[kth286]

you can check which rubber pads you have fitted.

turn front wheels out on one side and look into spring area from front.

use torch if equired and see how many drop down rubber blips there are on the outer edge of the rubber pad - parhaps feel with fingers.

if there are 3 blips for example and you put on one blip pads you will drop down by approx 18mm.

in addition the spring will drop down by approx 25mm

Okay had a look at it today and they have 2 blips on them, do you think the Sportline springs will lower it enough or should i change the spring pads to 1 blip one too?

Changing pads is the way to go to lower the car without changing the struts. If you put on the Sportline springs you should change to the shorter stroke struts at the same time as advised. On today's roads with numerous speed bumps and potholes reducing the ground clearance of any car should be thought about very carefully. To be honest the words "slammed" and "estate car" don't really fit together well - lots of manufacturers are actually raising the ride height of some of their estates to make them "Allroads" or "Scouts" or "Outbacks" so increased ride height is the high market end urban cool
Nice wheels by the way.

would i be right in saying changing from a 2-point spring pad to a 1-point pad will only lower the car 5 mm?

Also remember to allow the settling down of the springs, this may take a few weeks and the car may sit a little lower in time.

 

[kth286]

would i be right in saying changing from a 2-point spring pad to a 1-point pad will only lower the car 5 mm?

because of the suspension geometry there is a multiplication factor.

so a 5mm thinner pad gives approx 9mm actual body drop at the wheel edge.
