I posted a pic up a while back in another thread on the same topic, see if you can find it or I'll try putting another pic up again when I have some free time

For lowering springs, you can only get H&R and Eibach at the moment.

But it doesn't say if they are useable on cars with electronic dampening.

KW does have a DDC ECU kit that is useable for Coupes with electronic dampening.

i spoke with eibach and they stated they are not available for the coupe at this time? perhaps in development? i have seen them on a 4 door but not a 2 door... any insight would be appreciated.

the h&r spring are a bit too low for my tastes on a stock 18" rims set up.

If i use the program to check for car parts here at work, it says the Eibach kit is numbered E10-25-019-03-22 for a C250 coupe.

Fronts are F11-25-019-01-VA, rears F11-25-019-03-HA.
They lower 25mm.

Thank you for the part numbers... I spoke with eibach na and they are going to see if they can import them for me.

They are definitely available andrew c coupe, if not for you it could be a case of your location/Country not having been supplied as yet.

But definitely available here in Australia for the 2012 C Class Coupes

I'll try and find and put those pics up again of an Aust. C250 Coupe on Eibachs.

Does that mean you have to use KW DDC ECU kit if you have "Advanced Agility Pkg"?

I don't see why springs wouldn't work for those of us that have electronic dampening.

I've put Eibach springs on my M5 that has electronic dampening and the GT-R has electronic dampening as well and many aftermarket companies make springs for it...

I'm no expert on the subject, but my understanding is if you install lowered springs on any vehicle you alter the dampers bound and rebound limits compared to the original spring set that they're paired to.

They still work but limits are altered, if you lower to a large degree you also shorten the life of the damper quite substantially.

This applies for normal dampers and that's why most 'pros' recommend matching dampers to lowering springs sets.

I've used Eibach springs on alot of my previous cars without changing dampers and they all still worked just fine, but I did have a case on one vehicle where the dampers failed not long after the springs were installed, I replaced them with matching Koni units and that same car drove trouble free for years thereafter and the ride was noticeably better with the matching damper set.

Not sure about the electronic dampers, all I've heard in the past is to not use lowered springs on them unless they've been specifically designed and made for that purpose and specific vehicle, would be good to get more reliable info on the topic.

One of my customers told me that it's impossible or really hard to put lowering springs on electronic dampned springs. And advised me to not get that option. I ignored his advice and i am probably getting the KW DDC Ecu. I was getting tired of laying under my car to adjust the hardness everytime i had to transport more then 1 person.

@Showa: Yes, you will need the KW DDC Ecu if you would like to keep working with the button to adjust the hardness. I don't know if it is possible to install a coilover set and delete the adjustable hardness. Might trow up a code.

Just got a call from my KW importer.

In september they will finish the KW DDC Ecu kit for our coupes.
