The interesting rear suspension permits independent action of each wheel. Vertical movements of the wheels are controlled by two links, in which the upper link doubles as the axle shaft; and a rod, rubber bushed on each end as the lower. A third link runs from each rear wheel hub forward to the frame to transmit driving and braking thrust. Variable rate coil springs unitized with direct, double-acting shock absorbers are diagonally mounted at each rear wheel. Adjustment provisions in the rear suspension linkage permit variations in camber and toe-in to facilitate engineering studies. Front suspension is independent with high roll center geometry, and also utilizes unitized variable rate coil springs and shock absorbers as in the rear suspension. An 11/16" stabilizer bar interconnects the front wheels. The independent rear suspension design became the basis of the 1963 Corvette Sting Ray suspension. So that weight distribution during tests shall vary little if any, two fuel cells of rubber construction and total capacity of 20 gallons, are located on either side of the "CERV-I" at approximately the fore and aft location of the center of gravity. Thus, the amount of fuel in the tanks at any given moment will have virtually no effect on weight distribution.
