What is the function of the suspension system in a race car?

The function of the suspension system in a race car is primarily to maintain tire contact with the road surface. This is critical for performance because optimal tire grip is essential for handling, stability, and safety during high-speed maneuvering. The suspension system is designed to absorb shocks from bumps and other road imperfections while allowing the tires to move up and down relative to the car's body. By ensuring that the tires remain in contact with the track, the suspension enhances traction, allowing the driver to negotiate turns more effectively and maintain control, particularly under varying conditions and speeds.

Other functions of suspension systems, while secondary, may include improving ride comfort and adjusting the vehicle's height or alignment, but the primary goal in a race context is to maximize tire adherence to the track surface to achieve the best possible performance on the circuit.
