it alters the wheel base on the car, some cars i have done can be as much as 3 or 4 mm out----usually bent wishbones (ford) or even axle beams (corsas)
drive behind a car thats "crabbing"---thats exagerated setback !!!
yeah hence why it can only change set back, becouse when you lower the rear beam if the notchs arnt the same as you change each wheel one will sit higher then the other, giving you a bad set back, and it will change how far forward and back you sit on the thrust angle, so it can throw tracking out.
