info about modifying the suspension...4 those interested in the Group Buy
I talked to Evo Sport and this is wut they have to say:
AirMatic and ABC lowering
There are two ways to do this.
The first is new or different length "actuator arms" to fit to the shock/airbag assembly that fool the car. These parts are usually pretty poor quality, hard to fit and often provide uneven lowering at each corner. Installing them correctly is a black art but possible.
The second way is a computer interrupt that modofies the elctronic signal from the existing factory sensors. This way allows on the fly custom lowering front and rear with the twist of a potentiometer. Both front and rear wheels are coupled elctronically thorugh this device so lowering is even side to side. Fore and aft lowering are independent for flat or nose down stance.
IMHO the electronic device provides and infinite array of possibilities with simple adjustment and is far more predictable/reliable than the arms.
Changing the arm is the MOST common way of lowering the S class. For example, D2technik and Sprewell Racing lower S classes all day long and they never use a lowering module.
I cannot defend the quality of the part, but i've never heard of a part failing. The Amount of drop you desire depends solely on the length of the actuator arms. It isn't something that is common knowledge, but any good aftermarket car shop that deals with mercedes should know how to do it.
The rear drop is even simpler. The rear arms cross and you adjust the position where the arms cross to adjust the drop.
Changing out the arms + labor = $400-500
Lorinser module (not adjustable?) = $700-750
Kleemann Lowering Module = $2100
All comes down to how much you want to spend. The Kleemann module sounds real interesting; I would like to adjust the amount of drop. But then again, The airmatic function already allows you the raise the car. Adjustable height will just be a "Gee Whiz" function which is only used to impress people.
I've never seen a car with a lowering module. However, i've seen dozens of S class with changed out arms.
