Unsprung Weight Calculator

FAQs

How do you calculate unsprung weight? Unsprung weight is the weight of components in a vehicle that are not supported by the suspension system, such as wheels, tires, brakes, and some parts of the suspension itself. It can be calculated by summing the weights of these components.
