Support

The development of integrated plastic-steel applications has led to making radiator support from injection molded nylon that consists of a part with complex nylon contours, filled with a simple central steel piece. Any extra strength and rigidity needed in non-steel embodied extremities of the part is achieved by adding "ribs." Ribbing a flat surface can give that surface a tremendous amount of strength. Thanks to plastics' design flexibility, many different types of ribbing can be designed for a single piece, all with different important structural advantages.

A vehicle's chassis, as a term, also encompasses working parts exclusive of the body of a car. This includes suspension systems and brakes.
