We are increasing the angle of the inner hinge pins by adding shims to the 2 arm mounts that are closest to the rear of the car. The arm mounts are the "square ish" shaped plastic parts that you slide a Arm Mount Bushing into. If you add shims inbetween those arm mounts and the bulkheads, this increases the angle of the pins, therefore increasing your rear toe-in.
