Hi everyone! I just wanted to give all of you an update on our progress with the ABC conversion kit we have been working on for over 2 years. We have successfully converted our CL-500 to springs and conventional shocks. We are now in the road testing phase and hope to have a sellable kit by the end of 2011. I will keep everyone updated as the process creeps along. In order to successfully remove the ABC system you will have to remove and replace all 4 shocks, remove all the hydraulic lines and hoses, remove and replace the ABC power steering pump, replace the front lower control arms, and install sway bars and links. Not an easy conversion, but worth it if you are looking to replace the ABC system. We are going to convert another test car within the next 2 months and make a video showing the complete process.

Thanks everyone for all your support and business!

Adam

Glad to see Arnott replying to questions regarding their systems.

I ordered replacement bags for out R350 from them and everything went fine so I'm confused as to why they don't reply.

Their last post was 11/2011 so apparently they don't get email alerts from here or changed their email that was registered here.

I dont live far from Arnott
to end the mystery They DO NOT make an ABC conversion-just replacement ABC shocks-Here is their number if you need them - 1-800-251-8993
the replacement ABC shocks for a 2002-2006 w215 are $599 with $300 core and carry a lifetime warranty

Strutmasters does NOT make an ABC Conversion just an airmatic conversion-here is their number 866-597-2397

WRONG AGAIN, as usual travis.

The 2013 CL65 AMG comes with ABC suspension

The 2013 CL63 AMG comes with ABC suspension

The 2013 S65 AMG comes with ABC suspension

The 2013 S63 AMG comes with ABC suspension

The 2013 SL65 AMG comes with ABC suspension

The 2013 SL63 AMG comes with ABC suspension
---------------------------------------------------------

These are the luxury and grand touring cars that AMG Mercedes produces, and as such, they are fitted with the best suspension system AMG Mercedes produces.

The pure sports cars with the absolute lowest weights come with the traditional fixed suspension, but much more advanced then a $400 coilover that you have fitted.

Mercedes adaptive sports suspension.

And when you first removed your ABC system and replaced it with a conventional set up this is what you had to say:


conversion update:

you never really realize how heavy this car is until you take off the active suspension. the car tilts in turns and during accel/braking like any other car over 4000 pounds but you dont know it with the abc.
Please stop spreading misinformation on this forum.

Oh that's cool, they get alot of choices over in Ireland!
Looks like half of them are ABC systems, and the other half are the suspension I posted above. I was basing my research off of the Mercedes USA website where all of the cars I listed have spec sheets like this:

Alot of the time other countries, especially in Europe get all the fun options and even cars that we don't get it. I'm sure if you did a special order or to European delivery and then had it sent here you can get whatever option you want it if it's available for the build.

i see you're following me around elsewhere now lol. the abc system has body roll, so do the coilovers. it's more noticeable with the coilovers but the coilovers still perform excellently in not only straight driving but cornering.

i was solely referring to the sls. nothing new that you would try to misconstrue what i said. you say you like the abc for the sportiness, then why aren't we discussing the top tier of mercedes sports cars? doesn't really line up logically but that's nothing new coming from you lol. obviously the system is superior to the abc in terms of handling and reliability or the nicest sports car mercedes makes would have them wouldn't it?

wow, lots of bickering back and forth... I don't know anything about mercedes newest 200k+ cars so I have no input on any of that but I do know that mercedes ABC system is a phenomenal system that really is amazing in so many respects, yes it does add some weight but mercedes in general are more of a sport touring car than an all out performance at all costs kind of car... the fact that they can build a heavy touring car that can kill average all out performance cars is just another testament to the fact that when budget is secondary amazing things can be done

now to remove an ABC system from a benz just to save some $$ is just so far against what the car is all about to begin with... I mean why stop there, repairing a V12 is really really expensive so why not just throw a cheaper V6 or V8 in there when the V12 winds up having any issues... why not just put some 17" wheels and tires on when you need tires, afterall they are cheaper too... hell even the brakes are so expensive, next time there due you may be able to downgrade to 12" rotors and single piston floating calipers... brake jobs will be cheaper from then on too...

I agree with those that feel that the ABC is such a defining feature on such a fine car that removing it should only be done if your car is one step away from the junk yard and you just want to buy a little more time to use it as a beater before you junk it, otherwise why remove the ABC for coil springs??? that is just so backwards... anyone who thinks this is the right way to go probably just bought the wrong car to begin with... and no, I don't own a benz with ABC, but if I did I would do so knowing that when the time comes I will have to spend the thousands to restore the suspension on the 100k+ car that I bought, regardless of what I paid for it used... if not then you just bought the wrong car to begin with...

what really makes the 12 that much more to fix than an 8 cylinder? besides the cylinder deactivation feature there's not a lot of difference besides the fact that you have no room to fix anything in a 12 cylinder engine bay! lol i understand your point but your analogy is comparing apples and oranges...

the abc system is faulty at best. go to any high end mercedes forum and you'll see ABC ISSUES within the stickies....it's kind of pathetic coming from what is supposed to be the top notch car manufacturer

the w215 is still a nice car without the abc feature... i'm not sure why everyone thinks the w215 is basically a piece of shit without abc...seems to say a lot about the car you chose to buy, does it not?

if the abc system wasn't as faulty as it is then i would have had no problem investing maintenance costs to keep it up. but thousands of dollars every year just to have hydraulics is absurd from any logical persons standpoint....but then again so is owning any foreign sports car for that matter lol

in my particular situation, i put 30k miles on my car in a year. i bought the car with 58k miles and it had already had the abc pump replaced once... when it went out a second time at 70k...it was a no brainer as far as whether or not this system was reliable enough to maintain...

in my particular situation thats a new abc pump every year. not to mention one of my struts was already leaking. valve blocks fail, there's numerous hoses to fail, struts fail and a hydraulic pump that fails once a year is not up to my standards, and should have never been up to mercedes standards either (unless they are aware this system costs a lot to maintain, selling the cars to people with wallets big enough and egos big enough to maintain such a system) DING DING DING, congratulations you all just fell into mercedes' trap of sucking you dry even after you paid off the car. i think i've seen videos of w215's on fire because of abc related hoses ,(although corrected under recall) what gives?!?!

i respect your opinion however

edit: i chose the coilovers because i was aware that if i fixed the abc even one time, i would be venturing down an arrogant path of endless investment considering i want to keep this car for the rest of my life. perhaps a lot of you plan on getting rid of your abc equipped cars when they aren't "cool" anymore, but i absolutely love this car

i can also personally attest (since i'm the only person here who has experience with both abc and coilovers) that installing the coilovers is just about the same difficulty as changing the abc pump. except you only have to do it once instead of once a year....

cars are expected to have regular maintenance costs, that will never change. and parts for more expensive cars will obviously cost more. but there are plenty of 100k dollar cars that don't require thousands of dollars every year just to maintain one particular feature!!

i think everyone needs to wake up and get out of the past. there are probably extremely few people here who actually paid 100k for their w215. i would bet that most of us bought them for somewhere between 12k-28k. does it make sense logically to spend just as much as you spent to buy the car, on maintaining the abc over the course of say 3 or 4 years? i understand the people who bought these cars new maintaining the abc but lets be real. our cars haven't been 100k dollar cars for damn near a decade....ozan even pointed out to me that there are w215's in good condition selling for under 10,000 now....wow....

we all like telling people we drive a car with a 100k msrp price tag, but do we really have 100k dollar cars? for christs sake theres american parts (chrysler) ridden all throughout this thing. pretty sure our same transmissions are used in dodges, chryslers and the like. let's be a little more realistic and less arrogant. i know we drive mercedes, but we dont all have to fit into the stereotypes

The ABC makes the car but also ruins it too. It was a love hate thing with my CL. Loved the bi-turbo engine - hated the constant ABC break downs and thousands of dollars in repair bills.

The 215 CL is one if the best looking MB's ever produced. I would have removed the ABC on mine too if this were an option at the time. Without the ABC, the CL wouldn't be a half bad car to own. With it, the car can be a total nightmare. There is no reason that anyone should expect that a 130k+ car should be so undependable. I've never owned a car that was towed more than a CL. It was all due to the ABC suspension. What a freakin nightmare.
