I am considering converting the air suspension on my 2014 E63 AMG S awd airmatic to a coil spring setup. I'm looking at the Arnott Air Spring to Coil Spring Conversion Kit (C-3550) that's for the e/cls platform after lots of research it appears to be one of the best ones for the conversion. is there anything to be prepared for before doing so? Im not worried about the electronics i can get them codded out. would this conversion kit fit the e63 without any other modifications or parts? the whole idea is to get rid of the hydraulic and almost worn out oem suspension car is at 90k. is there any big differences between the cls and e platfrom or just that it sits a couple mm lower? any help or insight would be really appreciated Thank you all.
Some retailers list KW V1 and V3 as compatible with w212 4matic. Some others would list this kit as "except AIRMATIC". Then there are the BC Racing BR coilovers that are listed in some websites as "W212 RWD only" and others list as for "non-AMG W212s". There is also this Asian company called CEIKA that produces a kit supposedly for W212 AMG 09 and up (with many customizable options). None of them make any mention of what happens with the electronics.
Some time ago, I had found a company called Yellowspeed that listed a set of coilvers that supposedly would work in the AWD W212 E63S... just checked... no longer listed.
It really sorta sucks there isn't much aftermarket support for the facelift models while there seems to be so much more for the W211s.
Good luck trying to get this done and pls report back should you be successful at it.
update: everything went smooth with the swap, suspension feels almost the same however no more hydraulic future issues and expensive oem parts. i attached some pics of the result theyre height adjustable good quality materials would reccomend 100% if your shocks ever go out on a 212 or cls. however in the future i would look at kw's and check if they fit since they have crazy reviews but no issues with the scale brand.
Did you have any option for spring choices? how much adjustability do you get?
How easy is it to change dampening/rebound once installed?
Rebuildable? Can you use springs from various manufacturers? i.e. are they a standard diameter?
I had KW V3s on my Subaru STi and absolutely loved them. Once they were dialed they were amazing. Ride was better than stock on the road, and when pushed the car was always settled (along with sway bars and a proper alignment). Would gladly run KW V3 on the E63s if that was an option if replacing the OEM suspension. Not too concerned about the lack of integration with the electronics as I would just dial the suspension in and leave it alone. The OEM suspension is way too soft in 'comfort', and I would just leave it somewhere between a 'sport and sport+' setting. The front end needs a ton more support as it 'collapses' under hard braking.

nice work and thanks for this contribution
what did you do with the airmatic error message? Sorry if you already mentioned
whats your experience with this? i know they have a kit that over rides the adjustable shocks, but what happpnes when you remove the airbags? did you fulkly remove the compressors aswell?
I am also looking at coilovers. I have contacted Yellowspeed and BC and they both have kits that are compatible with my 2015 E63s AWD:
Yellowspeed part number for E63 AWD is YS01-MB-DPS099.
BC Racing has a kit (front and rear), part number is: J-23-BR, but since they sell individual spare parts for their kits they can sell just the front for $362 each. I did not ask for the rear because I want to keep the airmatic.

Do you have a link for this? My air suspension seems to be in the process of giving out and need a solution asap. Can you tell me what brand this is and possibly a purchase link please?
I'm very curious on the ride quality compared to the OEM setup. I ran the H&R springs on my 2014 E63S last year and they were fine, but they lowered the car way more than I expected (about 1 3/4 inches). I was looking for about a 1" drop and I like having the adjustability so I'm swaying more towards the KW HAS kit.

KW HAS def. the way to go. I had it in my car and the front was great... the adjustable links that come with the kit are absolute garbage. Buy metal links on eBay.
I agree on the HAS kit. That's what I have on my wagon. Tried H&R springs with links first and hated the feel up front. I also just replaced the shocks and struts on my car at 100k milest and can tell you it made a massive difference! I find that the car rides the best in sport mode when lowered. C or S+ are too extreme either way. My rear had become a tad too bouncy. New shocks fixed that right up. The only benefit of the KW links over the metal ones is that they have ball joint sockets on both sides. So you have more fine tuning ability where you can connect every half turn instead of a full turn.
I went down a rabbit hole of trying to create my own coilover setup for the rear of the BMW E39 touring and was never really happy with it. I worked with Fortune Auto and tried several shock valvings and spring rates. I would only trust a tried and true kit from a reputable company. Wagons are incredibly hard to get right in the rear. Especially with a divorced spring/shock where you adjust the height of both the spring perch and shock length independently of one another. In the end, I felt that a wagon needs a much heavier spring rate with a softer damper. It seems most kits do the opposite. Odd to think increasing spring rates improve ride quality but in my experience, that was absolutely the case.
