Detailed Product Description

This ADVICS disc brake rotor is constructed from high carbon steel, providing a balance of strength and thermal conductivity to reduce the risk of warping under heavy braking conditions. The vented design allows air to flow between the rotor surfaces, helping to maintain optimal operating temperatures during extended use. The non-directional brake surface finish ensures even pad wear and consistent braking performance regardless of rotor rotation direction.
