Electronic Lowering Modules: Are all equal?
I've done a lot of searching and can't seem to find the answer i'm looking for.
I'm finally biting the bullet and going to pull the trig on a lowering module but can't decide on the brand... the consensus is Renntech though i'm wondering if anyone has tried other brands Kleemann, Carlsson, Lorinser, Brabus etc. and compared back to back.
The literature states that dampening is "increased" but otherwise it's pretty vague. I think these airmatic cars handle like a bag of sht and would like the best handling solution.
Thoughts?![Confused](https://mbworld.org/forums/images/smilies/confused.gif)
Also, does anyone know the main differences between the v2 and v3 variants of Renntech's ELM?

Get the Carlsson 100% plug N Play great stance and you dont have to fool with it all the time. I installed mine last June it took 5 minutes and i have not looked back or given it a second thought.

The main differences: V3 can be plugged in to a laptop to change heights. V2, you can get the remote for.
Is the Carlsson one adjustable?

Can you get a remote with v3 or is laptop only?
If i go v2 how much approx is the remote?

I have V2. V2 is adjustable from the module. Remote retails for $600, IIRC, not worth it, IMO. My module is hidden in the passenger foot well

I have the v3 elm and can change height settings from usb to laptop. i have mine set at 2.2f and 1.95 r. i'm trying to reach renntech when they are back from holiday break. Not sure why, but when my car is at a redlight/idle, it drops lower...so not sure what height it is when its moving.....drop on renntech is up to 4inches

I assume this is the lowering module you have http://www.motiontrends.com/2006/200...lowering.shtml
I was reading your thread and a few others about the Carlsson and it looks very easy to install. However, how do you make all the height adjustments (via laptop or knobs on the ELM)?
Most critically, I am concerned about the car lowering itself above 60mph because according to Sonic MS my tire may rub the fender if I lower the car and it lowers itself at 60mph.

There are dip switches on the heads of the unit. My car has never rubbed at any speed and i have 20x11's on the back of my car. The whole idea of ToOning your air shocks is amusing to me. You set the ride height you want and use the setting on the console to do the rest. I just don't get the fascination with laptop shock tuning and $600 dash mounted air shock adjusters.![nix](https://mbworld.org/forums/images/smilies/nixweiss.gif)

Basically it sounds like all you do is plug it in, adjust the height & settings, and button her up. That's all I want, set it and forget it.

I'm not sure about the rubbing on my car, I thought the CLS' fenders can swallow a larger rim/tire size than an E. Right now I have the VRO5's with 285/30/20 in the back, I'm not sure about the offsets.

I just checked, it's 285/25. I don't want to dump it, just a nice one finger gap. Do you think it will work?

Love your car, FT! Those wheels look killer and the drop really compliments it...good job!
As far as the lowering module goes, I've got the Renntech V2, and I couldn't be happier. Install took about an hour and a half, but that included soldering and heat shrinking. I have it mounted in my center console underneath the cup holder, and I pretty much set it and forget it. A word to the wise...if you install this module, be sure to mount it in the center console BEFORE you solder all the wires. I didn't do it that way, and then had to cut all the wires and re-solder them.
Good luck!

I'm sure the off-sets are fine. I'll lower it just a little at a time.
The good thing is that Carlsson unit is plug and play. I am mechanically inclined but I don't feel like dealing with the cutting/splicing/soldering of wires that the Renntech unit requires. Moreover, according to Carlsson the lower module will also work on the W212

The Renntech unit is capable of greater adjustment and fine tuning than any of the other brands of ELMs out there. I don't get why anyone would incur the cost of any brand ELM only to set it once and never adjust it again; go with the lowering links if that's your plan.

The Renntech V3 unit has a second tab in the program that says "enable speed setting". Go to that tab, enable and say yes to the disclaimer, and raise it to like 200 mph. Basically, it states at what speed your car goes back to stock height (read the tab). When the car gets to about 10mph+, it will start raising back to stock height. I have mine set on 110 mph and around 80-90mpg, it starts it way back to stock- try 200 mph- give it a shot and chime back.

On the Renntech ELM, version 2 and 3, no cutting, splicing or soldering or wires is required to do the install. That's is simply misinformation. Numerous owners have done their own installs of the Renntech unit.

I remember a few months ago I saw an MB mechanic installing a Renntech ELM and he was busy splicing wires and exchanging harness wires to install it.
Is version three a plug and play like the Carlsson? Also, I don't want to have to use a laptop to set it up since I don't have one.

So does the V3 need splicing/rewiring? The Carlsson looks like it has its own connector between the wires from the car and the suspension control unit thereby making it a much easier install. I've reached the point where I am too lazy to mess with wiring, but that's just me.
I'm not anti-Renntech, I just want:
1. Easy plug and play (without splicing or rewiring).
2. Does not require a laptop.
3. Ability to cancel the speed-dependent lowering.

I'll contact Renntech and get the install instructions on the V3. I'm not familiar with it and don't know if it's any different to wire than the V1 or V2....
