What is the purpose of reducing unsprung mass?

[Val]

Reducing unsprung mass is aimed at improving a vehicle's handling. Here are the detailed explanations: 1. Reducing unsprung mass can increase the response speed of the shock absorbers, thereby enhancing the tire's contact with the road surface. 2. Improved tire contact with the road surface leads to better traction, which in turn enhances the vehicle's handling. 3. Reducing unsprung mass can also improve ride comfort. This is why many luxury cars use aluminum alloy to manufacture suspension arms—aluminum alloy is lighter in weight, though more expensive. 4. With reduced unsprung mass, shock absorbers can quickly rebound and compress when encountering bumpy roads, absorbing more impacts and thereby improving ride comfort. 5. During the rapid rebound and compression of the shock absorbers, the vehicle's tires can maintain better contact with the road surface for most of the time, further improving traction and handling.
