The Super Beetle camber adjusting bolt swivels in a capturing plate in the middle of the chassis. We feel that our camber bolts are more reliable than the factory VW units. While the VW bolt has a pressed on washer under the head, the Top Line bolt has a flat machined all the way under the bolt head. This construction makes it almost impossible for the washer to slip on the bolt. This bolt is located inside a rubber bushing on the inner end of the control arm. By turning the bolt head, wheel camber is adjusted. Sold each. Two required per car. If your car is lowered, please see our 88-2511 or 88-2511L Camber+ kits for extra adjustment.
