Damper stiffener extension and box-beam parcel shelf

1. Field of the Invention A structurally reinforced automobile body including damper stiffener extensions extending from the damper stiffeners to automobile body members rearward of the damper stiffeners, preferably opposite sides of the rear panel, the side panel outer extensions, the side panel outers or the rear frame members. A box-beam parcel shelf mounts at opposite sides to the region of the automobile body to which a suspension component attaches, such as the wheel house or rear inner panel. The box-beam parcel shelf substantially rigidities the automobile body, especially in combination with the damper stiffener extensions, which together form a contiguous structural reinforcement with the rear panel.
