Performance and safety are the best gifts for your car.
A key advantage of BONOSS forged active cooling aluminum car wheel spacers is the active cooling feature.
These BONOSS forged active cooling spacers come with petal-shaped grooves.
The grooves allow the external cold air to flow continuously inside the spacer when it rotates.
The air takes away the heat, actively dissipating heat for the braking system.
This enhances the heat-dissipating efficiency and improves road safety.
