Mercedes uses spring pads to raise or lower the car body. If you are using Bilstein "Sport" shocks you won't bottom out. The spacers are differentiated by which "bump" they are. Usually, the o.e. height is 4 bump front, and 3 bump rear. With 16" wheels (the most correct size for control, comfort and tire life) you would use 1 bump front and 3 bump rear to lower. P.
