SL55/63/65/R230 AMG: Coil over conversion. Anyone making it?
They currently are still only offering for SL500 and CL 500 models.
We just have to keep pestering them, before they get going on the SL55....Geo3
I too am very interested in doing a coiul over swap in the future.
The Best of Mercedes & AMG
From Strutmasters:
"Unfortunately, at this time, we do not have a kit to offer for that car. We have to be able to get a test vehicle in. Keep checking back though, as we do get new kits all the time."
they prolly will not do it as the market is very small.
now, on a related thought- i think the abc is the best thing that has happened to the sl class. abc (when working) is the best of both worlds- a magic carpet on a bumpy road as well as a stiff geometry when pushed aggressively.
my personal take on the abc? i will repair it as needed and enjoy it when it does not need repairing.
besides, it is not _that_ complex to repair - shocks can be had with lifetime warranty, hoses are updated (new ones rarely fail), valve blocks are indestructible and easily serviced when they leak and the tandem pump rebuilds are not that expensive.

I also agree with you "when working". I replaced my pump & hoses last year & I am cleaning my valve blocks in the next week or two because I have one side that fails when the car sits for awhile. I do know of the place to get the lifetime shocks & when needed I plan on replacing with those.
That said my issue is still with the "when working" & for this I would still consider the coilover conversion but I at this point I would have to really weigh the pros & cons of both because I have already replaced what I have replaced.

Prices are quite reasonable. Especially compared to factory OEM.

there is no way a coilover conversion is a better option for a street driven sl than the hydraulic system. i have driven all of my creations on that road and none felt as good or controllable as the sl did. huge dips, uneven road, potholes, and all types of other crap mid turn and the car felt better and more in control than anything else i have taken down the road. no way a coilover set up would control the same way. with coilovers you get one or the other, comfort, or cornering. i was amazed enough to write this about the stock suspension that i really think even a high end coilover is still a down grade.
just my .02. just a heads up for guys who plan to push their cars. you will not better the way the stock suspension keeps the tire in contact with the road. now if you plan to track the car alot.............................................. ............then......................still not sure you will better it.
"Hi-
Just found your coilover conversion kit for the MB SL500. Nice setup and it appears fairly straight forward to DIY.
Do you offer that kit for a 2003 SL55 ? If not, can the existing SL500 kit be modified for the '03 SL55?
Thanks
Rick
PS - If not ... why? What are the specific differences between the suspensions that must be resolved.
Perhaps I can get an engineering firm to resolve the differences between the suspensions. the OEM parts catalogs suggest it is almost a direct swap between the SL500 & SL55 in most years."

That is their answer. Thank you for your interest in our products. ..call me ...
Note he didn't answer ANY of my questions/concerns. Appears they are BS only ATT.
Yes, sure did. Below is an email from Brad Walker and above that is my answer to him. I included 5 pics, as he requested. I am waiting for his response.
"" Hi Brad-
Thanks for your interest.
The car is an '03 SL55 AMG. The suspension is stock ABC. Wheel/tire size is also stock at 255/40/18 Front, 285/35/18 Rear.
Attached is a side view, a closer view of RF wheel, and three pics with the SBC in normal (low), medium setting and hi setting. I put a tape measure on top of the fender so the settings should be obvious.
I know that the SL65 Black Edition has coilovers and it is also n R230 so mayny if not all dimensions should be the same. I believe Mercedes saves costs and development costs across the board with 'common' parts use so many parts will translate across the models of the same chassis and, likely, across models also. It is a matter of digging the info out.
If there is any more info/pics, just let me know. I know there are more than a few owners of SLs and other models with the ABC that are interested in a reasonable solution to the hydraulic system Mercedes uses. Not for better handling, but for cost considerations. The pump of the ABC fails in about 60K miles or so and each corner usually fails in under 80K miles. Arnot industries sells a built shock for a very reasonable price but many people I know would like to have an alternative.
The maintenance (small micron filter, fluid changes)is a necessity but many don't follow the guidelines. These parts are too expensive and fail too often.
Some of the more popular forums for the R230 all seem to looking for an alternative to the stock ABC system, especially new buyers who are caught unawares when they buy their R230.
Waiting to hear from you.
