Unsprung Weight
Unsprung weight is the mass not carried by the springs, such as wheels, tyres, brakes and hub parts.
What is Unsprung Weight?
Lower unsprung weight helps the wheels follow bumps more closely. Large heavy wheels increase it. Lightweight forged wheels and carbon-ceramic brakes reduce it. Rotating mass in the wheels also affects acceleration and braking.
How it works
The lighter the wheel assembly, the less energy the suspension must control when the wheel moves over bumps.
Why it matters for your car
Bigger wheels with thin tyres can feel harsher even if they look better. Changing wheel size should respect approved sizes for the car.
