Hey cthirtysizzle,
I have the European version of the AMG springs on my 99 C43. The car dropped about 1 inch. Not too far that it needs camber adjustment though. When I compared the stock springs to the Euro springs the only difference was about 2/3rds of a coil. Because the springs in the Benz are linear instead of progressive, you can have them cut and it will not make the ride bouncy and bottom out like it will in most other cars.
So my suggestion for that amount of drop would be to either cut the ones you have, or buy the Euro AMG springs. I have the guys email somewhere but I will have to find it. Let me know if you are interested.
