First: make sure your AMG wheels/tires have the same diameter as the stock 195/65R15 tires, which is about 25-inches in diameter. If you are going to primarly use these new AMG wheel/tire combo, go ahead and adjust with the AMG combo on.

Second: always adjust the self-levelling with all four wheels supported via an alignment rack. Do NOT use a lift.

Three: vehicle should be empty except for a full tank of gas, and spare.

Four: Make sure the bracket that is attached to the self-levelling rod to the swaybar is tight.

Five: Adjust the rod so that the inner-most hole of the valve-lever's is aligned with the a hole/depression on the valve-body. This is the NEUTRAL position. Use a small drift, allen key, or wire to do this.

Six: verify that this is the Neutral position by adding 100-lbs of weight to the rear (I use 150-lbs since I have stiffer springs), start the car, and see if it rises. You should be able to see the valve-lever deflected to the fill position. Adjust as necessary.

Seven: tighten adjustment rod, and take it for a test drive, without the weight in the rear. Visibly check that the lever is still in the NEUTRAL position after a spirited testdrive.

Good luck,
