Thank you all for the information and the opinions. It is good to know all available options.

Just to follow up with the Strutmasters update. I called and was told by the lady on the phone that they currently no longer offer the kit. She think they may be trying to redesign the kit but she is not sure. If they are to offer it at all again, which she is not sure either, it will be at least 2 to 3 months out. She also said that Strutmasters was the only company that conversion kit.

Has anyone tried to retrofit the Mercedes oem sl65 black series coilovers ? Wouldn't they work and be even better than the strut masters conversion ?

Anyone know how much they cost and the part numbers ? Perhaps they cost too much from mb

Have you asked yourself why Strutmasters is no longer offering the R230 setup or why, if it is offered again, it will be in a re-designed form?

Each strut costs about the same as a basic ABC strut.

Went with a re-manufacture Arnotts right rear shock from Parts Geek, and had a local Indy installed it. I did the fluid and filter change myself before install the new shock by following the a post in the forum, it was easier than I thought. The car suspension is good again, for now. Thank you all.

By the way I also discovered the windshield washer reservoir was leaking with a small crack, when I tried to fill it up with the fluid. With some work, I was able to slide it out (with the hoses still connected) after the front passenger wheel cover was removed, and glued/repaired the crack.

I got r230 conversion struts from CEIKA


I got the conversion struts from CEIKA, You can adjust the height, no swaybars needed. Drove 140 mph speed, no problems.

And 3) I have yet to figure out how to wire that light fix module correctly, as the wires in the manual do not match up with those under my dash. I don't have an endless amount of funds, so, all in all, I am satisfied with the conversion since it makes for 1 less bill on a vehicle that is a joy to own, but is very expensive to maintain. Still searching for the proper wiring for that light fix though. Any help with that would be greatly appreciated.
im looking to do the same my main question is about the existing pump.. do you leave it as is and just cap the old lines at the struts and do you pull the fuse for the abc pump so it just runs low pressure???btw there are several u tubes on the light fix module which explain install...

There's 2 different solutions.

You can loop back the ABC pump output hose so that it feeds right back into the reservoir, or you can replace the tandem ABC/power steering pump with a power steering only pump.

You cannot just cap the lines.

I created this solution back in 2017
here is how to on a CL W215 Just follow the Idea no fuses nothing just loop
you can remove everything if you want, even the abc cooling radiator. good part with that is that if you have a V12 you can easy switch to the full size intercooler radiator

Any electronic geniuses in the forum??

Gents, I am pretty sure that in this forum there are individuals capable of figuring out what value of resistors are necessary to 'simulate" typical ABC inputs. That is basically what Strutmasters did, they measured the Ohms values on the Strut itself and placed a bridge on the connector..! Then build a box for sale! I have done the same with some old electronic sensors, but have no good info on these hydraulic struts! If anyone have done experimentation on this, please let me know! The shocks and suspension arm sensors are just plain rheostats!

Thanks!

Looks like they tied it in at the abc module, not the individual strut sensors themselves.

CDK, if the tree pin cables are traced to the module, it will be a lot easier to put a standard rheostat and adjust to the required values. I wonder where can a "electrical diagram" of the system could be located to determine the polarity! So, identifying the points 1,2 and 3 in the struts and the values, this will be a piece of cake at a cost under $5.00.

I haven't seen or used a 'light fix' module, but my guess is that it is a CAN filter programmed to filter out ABC error CAN messages. Resistors might work for some sensors, but the ABC module looks at current draws at all solenoids, it reports errors if levels don't change as commanded, etc. If you don't have DAS, buy the box and don't worry about it. If you have DAS or easy access to DAS, code out ABC.

Happy to hear that it worked for you. Can I ask you wither that conversion of struts affected the hard top (does the car convert smoothly) as I heard the hydronic system of ABC is connected to the hard top as well.

ABC has nothing to do with the Hard Top Operation. 2 separate hydraulic systems the former works off the power steering pump the latter has its own hydraulic pump in the trunk.
