** Calipers must be mounted facing the rear of the vehicle.  Original and new knuckles can be swapped side to side.
** Calipers protrude 0.7" from the wheel mounting surface of the rotor hat.  The outside diameter of the caliper measures approximately 16" from the center of the spindle.  Check your caliper clearance as most 18" wheels will clear, but poorly designed 17" wheels may not clear.
