Electronic Lowering Modules.
What are the current options for Electronic Lowering Modules for a 2005 SL55 AMG? Got mine lowered with the Start system, but it's not enough drop for me...
What's your experience with them? Any problems raising the car to "HIGH" before entering parking garages, etc.?
Anyone wanting to sell one, please PM me.

SDS should be a good drop leaving 2 or 3 finger width of height. Links I think are the next best thing, modules are expensive and require wiring installation, why go electrical when you can go mechanical to make it simpler. MY SL55 in the pic below you can see the stance was lowered using SDS...

my car has the Brabus lowereing module installed and no problems so far. There are no user settings, and the car still have the normal height ( lowered ), raised one, and raised two. But technical support from Brabus dealer in Hong Kong is not as good and not attentive though.

SDS is star diagnostics (computer reprogramming of the stock computer to lower suspension height for ABC system).
Go with adjustable links to reset the physical air suspension zero height sensor as others suggested - 300 or less, removable, no wiring, no real issues that I know of.

The car will adjust upward 0.5 and 1" respectively from the lowest position (similar to stock oeration) but the height will not be "stock" in overall clearance since it is based off of the lowest point. Typical lowering will make the 2 lights on/1" raised position closer to the stock zero lights position.

With a lowering module, you can vary the voltage to the sensor directly - which will allow you a greater deal of control/settings (if you feel this is necc - though I'm not 100% sure it is..). You'd be able to put the car into full highest height SUV mode and lower it so low that it won't drive.

You have hit the end of my knowledge here on the modules, and may want to contact Renntech or similar mfg at this point for your questions. I know you can vary the settings on the module and use it to select nearly any desired ride height, but I do not know how it interacts with the stock ABC height adjustment button/lights on or off/stock system.
FWIW - I have just bought a set of AAR links to try out in my SL65. I may try Star Dx if they don't work out to satisfaction. I don't like the module/hacking into wiring idea or price, especially given the lack of clarity on how they function in reguards to stock operation of the ABC system.

FYI: As I previously mentioned, I already lowered the front and back via the Star System, for $150, and while the front was low enough, I was not completely satisfied with the back. I wanted another 3/4" to 1" drop. Yesterday, my local tuning shop suggested we drop it further at the rear using washers...simple and cheaper than the module/lowering links!The good thing about dropping the car via the Star System is that its done via computer only...No wiring, etc. and if you have an extended warranty like me, you'd probably feel better not tempering with original components.

Lowering links are an easy install/removal (from what I'm told/have read). Shouldn't mess with the extended warranty (which I also have, also from what I've read). How are the washers going to provide a lowering solution?

I haven't looked into why exceeding 3v's is bad, but its just what I've read on this forum. On another note, I really don't know any good shops that recommend using washers to lower the car. I had a brief discussion with Wade Williams (sponsor EURO.SPEC). He is a former Mercedes dealer Tech and RENNtech employee And now owner of Euro-Spec. If anyone knows if the washer technique is any good. He would know. I would deff PM him.

I have STAR DAS, I tried lowering my SL55 car via STAR. However I didn't want to exceed 3volts to each corner. Anything higher than 3v's was just not good enough for my taste.

From what I understand, the washers are placed between the link supports and the frame of the car, where the links are originally bolted on. For the front, the more washers you put in, the longer the link or push on the sensor switch. This has the same effect as mounting a lowering link and increasing its length. The net is, the longer the link at the front, the lower the front. For the rear, the shorter the link, the lower the rear...I can only speculate as to how they mount them at the rear, but it works...
As for my final decision, I decided to try the Lowering Links.

Lowering links work similar to washers, but I think I would recommend the link idea over washers for several reasons:
1) Can remove and replace with greater ease for dealer service if needed.
2) More adjustable than washer placement. Likely also easier to level out.
3) Keep the stock sensor position bars completely stock (not sure if rear would need to be bent/cut with the above idea). etc.
In related news - my links should be here this week to try out as well
Hope the thread helps you and others with current options for lowering.
