I have a Renntech DLM Digital Lowering Module v3 for sale.
Its in perfect working order, just uninstalled from my CLS550 as i wanted to put ride height back to stock as selling the car.
If you don't know about it, it gives you tons of control - plugs into computer / tablet and lets you adjust individual wheel height, you can set it to raise or lower over certain speeds - i.e. it will drop down when you come to a stop, but then when you cross 10mph raise up a certain amount... Or when you're going at faster speeds, have it lower down.. You can set it to whatever you want!
