The performance gain achieved by reducing the wheel mass (Un-sprung Mass) can be quantified using a factor of six. This means that to achieve the same performance gain by reducing the body mass, it is necessary to remove six times the wheel weight saving.
以上簡單說來就是輪下偷輕 1kg=輪上偷輕6kg
Example
A saving of 2Kg Per Wheel x 4 Wheels = Removing 48 Kg from the Bodywork.
In some instances, Dymag Carbon Mag wheels have reduced the wheel weight by up to 5Kg / Wheel, which equates to saving 120Kg from the bodywork to get the same performance advantage.
