In some modern cars, flexibility is mainly in rubber bushings, which are subject to decay over time. For high-stress suspensions, such as off-road vehicles, polyurethane bushings are available, which offer more longevity under greater stresses. However, due to weight and cost considerations, structures are not made more rigid than necessary.
1976: Radiator (AMC Matador), engine (Chevy 350 V8 2-barrel carb, cylinders were over-bored, requiring larger pistons and rings), transmission (TH 400: Turbo Hydra-Matic), differential (Spicer 44), front lower A-frame (Ford 56 Thunderbird), front upper A-frame (63 Lincoln Continental), steering was rear drag link until 1980, pitman arm bushing ...

The 2-door sedan, 4-doors and station wagons still had vent windows but the "DirectAire" system was an option for these models. The ignition switch was moved from the instrument panel to the steering column, in compliance with Federal regulations. The steering wheel and column-mounted shifter locked when the key was removed.
The rubber subframe bushings are also replaced with solid aluminum counterparts to increase driving response. [36] [37] Weight was also reduced by 60 lb (27 kg) as compared to a standard ZL1 due to thinner rear-window glass, fixed rear seatback, and lighter wheels and suspension components. [38] [39]
The bushing in line with the wheel can be kept relatively stiff to effectively handle cornering loads while the off-line joint can be softer to allow the wheel to recess under fore-aft impact loads. For a rear suspension, a pair of joints can be used at both ends of the arm, making them more H-shaped in plan view.
The three-way ventilation system consisted of two vent windows (driver- and passenger-side doors) and an additional vent located at the cowl. Steering effort was reduced with an increased steering ratio. A new channeled steel front bumper was attached directly to the extended frame rails, which provided increased rigidity and a smoother ride.
It featured a tuned version of the new 283 CID V8 and a specialized tubular space frame chassis. However, after a rear bushing failure retired the car during a 1957 Sebring race, the AMA announced a ban on motor racing in April 1957 for member companies like GM, leading to the cancellation of further developments of the Corvette SS platform.
