Changes to the Suspension:

If a “lowering-kit” and /or light alloy wheels from accessories which have not been approved by the vehicle manufacturer are used, wheel alignments which deviate from the alignment specified in design may occur during travel.

Even if the adjustment of the axle geometry measured on a standing vehicle is correct, changes in the body height and positions of the wheels during travel can lead to changes to the paths of travel of the wheel suspension.

For this reason, uneven wear is pre-programmed.
