What is skid-pad?

A skid-pad is a circular track surface, designed to test the maximum lateral acceleration of a vehicle before it loses traction and begins to skid. It is a commonly used testing facility for vehicle dynamics and handling, especially for race cars, as it enables the driver to test the limits of the vehicle's maximum grip. Skid-pads are typically made of a smooth and durable surface, such as concrete or asphalt, and are usually located at automotive testing facilities or racing circuits. They are an essential tool for car manufacturers and racing teams to develop and refine suspension setups, tires, and overall vehicle dynamics. The performance of a car on a skid-pad is usually measured in terms of lateral acceleration expressed as a g-force. Overall, skid-pad is an essential facility that helps to improve vehicle handling, performance, and safety.
