spindle is a heavy duty forging that is approx. 1.75" taller [balljoint to balljoint] than the OEM spindle. This basic geometry change increases the camber gain during suspension compression [allows the tire to lean into the turn instead of away from the turn]. spindle also has a pin height that is 2" higher than the OEM spindle. This means that your car will sit 2" lower than it would with the OEM spindle.   For use with Disc Brakes.
