The different degree blocks are used to change rear toe-in or sweep in front. It changes the pin width also. You can have 3 degrees of toe-in, but have the inner hinge pins closer or farther apart. This alters how the car rolls over. Generally running narrower creates more chassis roll.
Rear anti-squat is adjusted by adding or removing shims under the pivot blocks.
