SL55/63/65/R230 AMG: GOODBYE ABC, SL55 ABC TO COILOVERS FINALLY!
When (not if) I need ABC repairs I had planned on Arnott rebuilt struts that are guaranteed for life. When the ABC pump fails I guess that I will bend over and buy a new MB tandem pump. Or maybe try a rebuilt?
My car is almost 100% original except for the factory SLR wheels and trunk spoiler. Not selling the car and I am not sure if having the problematic ABC system replaced with an aftermarket suspension is going to help or kill the R230s already deflated value???
Bottom line is that Coilovers are great! Virtually every race car has used them for over 60 years. But I am not sure the SL65 would benefit from SL350 Springs?
I doubt HR has done enough R&D testing to fine tune their springs and shocks to work perfectly with the weight of both a V8 and a V12? Are the shocks adjustable?? Dash mounted Electrically adjustable shocks would be great!!! That I would probably buy into?
The MB Chassis type 113 (230-280SL) used a compensating shock attached to the rear diff. They all failed back in the days when the cars were driven. They have all been replaced with just a compensating spring and that is not a problem for resale.

Front sway bar p/n 230 320 21 11 Retail $950
Rear sway bar p/n 230 320 22 11 Retail $705
Obviously the SL65 BS parts are not the way to go! I will have to find some used SL350 sway bars from somewhere.
Thinking of having some custom made struts and springs.
All are available through the Mercedes-Benz dealer network or may be purchased, out of Florida, in a kit (see in PDF).
Hopefully, someone can add more; possibly a step-by-step DIY with photos and/or video?
