    What is A G-Body Suspension?

    A G body suspension is a type of suspension system found in General Motors vehicles. It was introduced in 1978 and used in various vehicles throughout the 1980s. The G body suspension is a multi-link design that utilizes a set of coil springs, lower and upper control arms, a central strut, and stabilizer bars to provide an even ride quality and improved handling characteristics. The design also allows for a wide range of suspension tuning options, as the various components can be adjusted to increase or decrease the stiffness of the suspension.

    The G body suspension is used in a variety of vehicles, including the Chevrolet Monte Carlo, the Pontiac Grand Prix, the Oldsmobile Cutlass Supreme, and the Buick Regal. The system is known for providing a comfortable ride and excellent handling for these cars, and many aftermarket parts are available to improve the performance of the suspension further.

    Types of G Body Racing Suspension

    Several types of G body racing suspension are available, but the most common are coilover, leaf springs, and torsion bars. Coilover suspensions, which feature adjustable dampers and spring rates, are famous for their versatility and ability to handle various driving conditions.

    Leaf springs are more straightforward but generally provide a softer ride, and torsion bars are often the choice for a firmer, more precise ride.

    Coilover Suspension Setup

    When setting up a coilover suspension, several key factors are to consider. The spring rate, or stiffness, of the coilover, should be chosen based on the type of driving conditions the car will encounter. Too soft a spring rate can cause the car to oscillate during cornering, and too stiff a spring rate can cause the vehicle to bounce and slide.

    The dampers, or shocks, should also be adjusted to match the spring rate, and shock absorbers with adjustable damping are available for this purpose.

    Leaf Spring Setup

    Leaf springs provide a softer ride than coilover suspensions but require proper setup to ensure optimal performance. The main parameters to consider with leaf springs are the number of leaves, the thickness of the leaves, and the type of material used.

    The number of leaves determines the stiffness of the suspension, with more leaves providing a softer ride, and the thickness and material of the leaves affect the spring rate.

    Torsion Bar Setup

    Torsion bars provide a more precise ride than both coilover and leaf spring suspensions, but they require a more complex setup. The main parameters to consider with torsion bars are the length and diameter of the bar, as well as the material used.

    The size and diameter of the bar determine the torsional stiffness, which affects how the car responds to cornering forces, and the type of material used affects the spring rate.
