Because he was wrong like I was when I thought I was going to just shim mine.(most cars you can!)

Then I took a closer look and realized that shimming would only change the angle of the rear backing plate with the brake shoes and would not do anything about wheel alignment since the axle that the wheel bearing and hub rides on is welded to the rear H-beam.

Trust me! It is not possible to shim the Mirage!
