Rear Quarter Panel

The rear quarter panel is the body skin, or sheet metal, that runs from the rearmost part of the rear door edge, around the back and to the rear door on the other side of the car. On many cars, the rear quarter panels are integral with the roof. The rear quarter panel is composed of an outer skin and inner panels. The inner panels are reinforcements for the rear of the passenger compartment, the trunk, and the wheel housings. Without the inner panels, there would be severe vibration and weak construction in the back of the car.
