Just recently installed KW v3 on a c350 4matic sedan, and noticed that the rear coils don't lower the car as much as I expected. The coils are bottomed out on the rear and it doesn't look much lower than stock. Has anyone experienced the same problem?

Did you remember to remove the spring pads before installing the new spring and perch?

ragulan89

I didn't do the install myself the shop did it for me. I thought the spring pads come out with the factory suspension since it was a full suspension swap....Am i right or could that be the problem? This wasn't just a spring swap. it was a full suspension swap.

In a coiloverkit to the W204 you still use a traditional spring in the rear but the usually comes with a adjustable pad between body and spring.
If the stock spring pads arnt removed you will not get the low car your looking for. They dont always fall out when removing the stock spring.

Correct. Do you know the spring rates? Some useful links:

here's a side picture to show the car height. The rear suspensions are literally bottomed out and only at this height. The front can be dropped another 1-1.5cm from what the garage said. I'm gonna go through the factory parts and see if the spring pads were removed. Anything else that you guys can inform me of

Check the install instructions link I provided. They provide the minimum possible drops, based on a front and rear "B" dimension, measured from the center of the wheel to the fender edge. Check it vs yours.

Setting the drop on the rear is straight forward. The top of the rear spring is captured in a recessed seat that keeps the top of the spring centered. So the springs don't get loose at full droop when height is set to minimum.

Setting the front height requires tightening the spanner nut until there is just a little preload on the flat coiled helper spring.


What BUGS me is that you have a 4MATIC and KW-V3 does not list 4MATIC springs for your car. Do you have any part numbers?.

3k down the drain bro.... send them back theres no noticeable drop.

kevink2

likely not KW's

EuroJDMBenzo

wow.. (((( it barely looks dropped (((v

slowc

Should of hooked him up with your setup

kevink2

Unfortunately, he did not generally seek advice, from what I saw. He still needs to check if the top spacer was removed. Based on the rear Motion Ratio, that could be his problem, but I still doubt he has V3's up front.

Perhaps you could have figured out the proper "B" dimension for the rear, that was in the instructions I found for the OP?

Hey guys sorry for the late reply been busy with work...So here's the update so far.

The car has settled a noticeable amount and kevink2 they are the KW V3s I looked over all the parts prior to installation. The KW V3 website doesn't show the v3s for the c350 but the c300 4matic is there online. That's the one that was ordered. Heres the details from KW website.

KW Coilover Kit V3
KW Coilover Kit V3 Mercedes W204 4matic
Part #: 35225036
Front Lowering: 0.8" to 1.5"
Rear Lowering: 0.2" to 1.4"

I've taken it by some garages to see if the coils can be lowered anymore but they say that the front is bottomed out and the back they can't see unless they can't really tell unless they pull out the suspension. Slowc definitely right 3k down the drain if this is the lowest i can go!!

Kevink2 I know you've been telling me to check the top spacers but how do i check that, all the shops are saying that everything has been installed correctly. My last resort might just be to take it to a shop and pull the suspension out and re install them fresh again. Any other ideas?? I'll post updated pictures soon.

Cleanbenz

Unfortunately I think you need a shop to pull the rear suspension to make sure the spring pads were removed. As for the front, if they are spun all the way down then there's no fixing that unless you buy a shorter spring set which will most likely make the ride too stiff for your liking. If it were me I would take everything out and get a refund.

Cleanbenz

Are you sure the idiots that installed those don't have the lock collars spun the wrong way? It looks like that's max high not max low. Stranger things have happened! Jack up the front and take a look at where the collar is.

Any shops you guys can recommend in toronto/markham/scarborough ontario area? I got these installed at speedstar in markham.

ragulan89

Just called speedstar, and the guy i was dealing with says the coil overs can only be installed one way, if they were installed incorrectly they wouldn't be seated correctly. I told him I wanted to return it and because of the time that I've had it unfortunately I can't. So i guess my only other option is to go with shorter springs....But I will take it to another shop and get them re installed to see if anything changes. Any suggestions on shops??

Hey guys heres the pictures of the stock suspensions that were taken out of the car..maybe this will help get more information
