Let me get this correct! In order to lower a MBZ all you need to do is change the spring pads and not the spring? The need for new aftermarket "lowering springs" is moot unless some radical slamming or stiffer ride is desired! So companies like Eibach which make sport springs actually do not lower MBZ because they use the word "PAD" in the column for "average drop front & rear" for their MBZ products. Although their sport springs are probably needed for the sportier/stiffer ride.

It is my understanding from the blurb below that the customer must adjust the height by using his own MBZ OEM pads he gets from the dealer. I found this Eibach information for MBZ at Discount Tire Direct:

(Pad) Mercedes vehicles lowering amount may vary .5""-2"" depending on options and equipment. These heights may be adjusted through Mercedes pad system. Please consult your authorized Mercedes dealer if additional ride height adjustment is needed.
