Is it me or...

Silly question - why does the blue 'longer' spring have 10 coils against 11 coils for the red 'shorter' one? Looks shorter too, possibly down to the pics?

I'll get a pair in a week.

I can ask Phil at Peach Parts about it Monday, and I will let you know what ships to me as the "300 CE Sportline II" kit. I have a feeling since the drop is less than an inch and its for the cabriolet (heavier than coupe) it will be the longer spring out of the two, but we shall see.

Yes it will be good to see, thanks for that Robert.

I have a feeling this is not going to be an easy search and that MB do not use a part number for the short spring anymore. You should have an MB part number stamped on the last coil of the springs, even that number would tell me something. I have pretty much all the Sportline Spring part numbers for the Cabriolet (care of another member on here) except the red rear one.

Can you please do me a favour and measure the ride height of the car before and after the fitment, take pictures of the springs in there at the moment and the new ones. I'd be very keen to see the markings, the part numbers and the ride heights - good data to have and share.

Be glad to.

Here are some shots of the springs that are currently on my cab as well. I'll look for numbers when they come off.

As for the measurements, I will measure from the ground to the fender as well as the center of the hub to the fender. I just mounted staggered 17" AMG IIs and had rubbing up front so I have 235s on the 8.5 rears and 215s stretched on 7.5 fronts. I don't think it will be much, but I am thinking that's not going to be an equal sidewall height. The measurements should prove that anyway.

Thanks for that Robert, looks like you have the long blue ones: bet you can hardly wait for the bits to arrive and get them fitted........ :):)

I took that photo of the springs and yes, it is a front and rear spring. It was just to show the paint stripes. You cannot order a red or blue, you get whatever Mercedes sends you, and you adjust the height via the spring pads as stated in the EPC. The difference between any red & blue springs of the same part number will be approx 5mm.

Inspector, if you replaced rear suspension components and the rear end is now significantly higher... I'd suspect the link attachment bolts were tightened with the car in the air, which is a BAD thing to do. However if your subframe mounts were collapsed and you replaced all four, that could change the ride height a bit. It would help if you posted a photo of the problem, or took measurements as shown here (to wheel center, NOT to the ground).

Thanks Dave,

The car definitely had the suspension bolts tightened sitting on a ramp hoist. Was done by a man with 20 years experience working for MB, Forman of NZL's largest Dealership, Factory trained on 124's.
ALL suspension rubber was changed and this is known to raise the ride height. I'm half a planet away from the car at present so I can’t measure and it is academic in any case, I estimate the car would have raised by about 3/4".

The 5 mm you refer to above, that is spring length yes? Which would correspond to 10 mm ride height change....??

I am on No 1 pads now so cannot go lower. Note also that the rear rubber for these now carry 129 & 210 part numbers, I wonder if this also contributes to the effect I’m noticing.

Is there any way at all to influence what the man at MB sends? Is this possible?

Note that there appears to be a separate part number for Sportline Cabriolet short front springs' 124 321 40 04. Does this make sense to you?

If all else fails what springs out there are the closest to the Sportline springs; H&R’s?? & can you run them with the standard Sportline shocks and bump stops??

OK, that makes sense, a 3/4" change is not a big surprise. And yes, approx 5mm difference in spring length. The rear link part number changes have no effect on ride height, btw. You could always cut a 1/4 coil off your springs, this would have nearly the same effect, while making very little if any difference in spring rate. There are a plethora of Sportline springs, so if you need a shorter one, just figure out which that would be and order them up. H&R and Eibach only make a couple of different spring sets, you should have far more options and adjustability with the OE springs.

The different part numbers for the springs are due to the "points" which determine the weight of the chassis, based on optional equipment. The Cabrio Sportline uses #40 or #41 front springs depending on the points; although it appears there is only a single rear spring spec'd without SLS, #34. I don't have specs for the #34 in my spring spec spreadsheet as I've never had a reason to buy them and measure.

Most likely the problem you are seeing is not that the rear is too high, but the front is too low. As the front struts wear over time (usually a few years / 10's of k's of miles), the front end will drop 1/2-3/4". New struts will raise it back to normal, then it will gradually sag again. The rear shocks don't do this - not sure why it's only the fronts. It took me years to figure this out, after measuring my ride height a couple times per year over many years, with new & used struts. At any rate, if you are trying to get to a certain ride height, you just need to tweak the springs & pads as needed...

Thanks for that Dave,

Front and rear shocks/struts are MB-Genuine new as well as the LCA's & steering components - she got one h5ll of a birthday!

Front has raised too by about the same amount, but from memory the Mech said I can drop that because the pads were not No1's. I don't remember exactly but the front is not so much a concern as the rear.

Is there any way to use a sedan Sportline spring in the rear? Is there a way to substitiue for something that carries less points - will that drop it a bit..........??

The smaller one in the picture in post #1 is the rear, at the bottom it looks like this is open ended, is that right, or are they closed like the fronts.
If they are open at the bottom, is it just a matter of triming a little piece off and it will still sit correctly in the springlink??

All the rear 124 springs are interchangeable, however since there was only one Sportline Cabrio rear spring spec'd in the EPC, you don't know which spring would be an acceptable alternative.

Front and rear 124 springs have open coils at the bottom, and yes yoy can trim off a bit and still have it sit correctly. If you go this route, make sure to only trim a small amount at a time (i.e., 1/4 coil). If you cut too much off, you'll have to buy new springs to fix it.

:eek:

I was thinking cars that have a lower axle weight at the rear, anyone got a list of rear axle weights for the 124's - worth a punt, I'd have thought........??

Does anybody know if MB offered a rear "short" red spring for the Sportline E320 Cabriolet - Non SLS?
For the record they do, here's a picture of a set going in mine, part number 124 324 34 04 - red.

Sit 5 mm lower than blues and have made a huge difference to stability - I guess springs wear out too.....??

Sorry so late to the party.

I did get the red marked springs installed with the sportline LCAs, all new bushings struts and shocks front and rear and the car ride height dropped aver the course of these last two moths to a total of just under a 1/2" in the front and rear. It looks great with the 17" Monoblocks on there and the ride is just outstanding. I am considering the steering box now since that's all that is left for the mechanical conversion. I am very happy with the results and thanks to Phil Reinhart for helping me with the parts and may he rest in peace.

I have to agree re the ride, like a limo but firm. Very, very addictive.

What surprised me the most was the improvement in ride quality. I had the standard blue (long) option springs in there with 200 000 kms on them from factory. I'd replaced all suspension components with MB-Genuine parts except the springs, noticed the ride height sat up 15 mm or so - so I started looking for an option to drop that a bit. Stumbled across these red option Sportline springs which meant I could keep the springs original but have it 5 mm lower that std Sportline height.

But, what I did not expect was the drastic improvement in ride quality over the old springs, I had no idea springs alone could make such a difference, when the only difference was a new spring with the same rate etc but only 5 mm lower. Go figure....??


Looking forward to getting the fronts done now!!
