The problem with something like this is it will comprise the springs compression ratio. Consequently you will run into problems like bottoming out and worse you could cause variable spring rates on different wheels that could cause you to lose control of you vehicle in tight turns. This solution is only good for drag strips!!!
Get yourself a set of lowered springs installed if you want your benz lower. Using clamps or the "spring cliper" on a stiff german chassis and suspension is about as insane as cutting of a coil or two for the same effect
just my 2 cents.
