it depends on what handling characteristics you want more anti squat adjust the up and down angle of the hinge pins tiltng the hinge pins so the rear points down increases forward bite and reduces side bite but will accelrate better through bumps. raising the rear of the hinge pins does the opposite reduces forward bte but increase side bite makes it jump flatter and better accelartion in smooth flat areas
i believe the kit standard setup for a b4 would be 2 degrees
on my x6 with no shims its 4 degrees
