Wondering if Members could assist me. 2009 e89 Z4 that cannot not be aligned to factory spec in the rear. Here are the results of the 4 wheel alignment.

Front

Initial: Final: Manufac Range


Camber -0.5 (Lt) -0.1 (Rt) -0.5 (Lt) -0.2 (Rt) / -0.8 to 0.0

Toe -0.12 (Lt) -0.15 (Rt) 0.12 (Lt) 0.12 (Rt) / 0.9 to 0.15


Rear

Camber -1.8 (Lt) -2.1 (Rt) -1.1 (Lt) -2.1 (Rt) / -2.4 to -2.3

Toe -0.03 (Lt) -0.34 (Rt) 0.17 (Lt) -0.04 (Rt) / 0.12 to 0.19


These are the best adjustments that the garage could achieve. I asked what could be causing this, their suggestion was frame out of alignment. I had this checked and it is to factory spec.

The car seems to track fine without any pulling to right or left

The right rear tire had to be replaced because of inside tire wear.
What could be causing this and how would I check as well as solutions?

Thank-you for your help
