Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a plain disc finish and a zinc silver coated hat to resist rust and corrosion, extending rotor life. The rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional slotted and drilled surface pattern helps channel away dust, gas, and water, improving braking consistency and pad contact. With an overall height of 120.7 mm and a solid bolt pattern of eight holes, this rotor is designed to meet the exact specifications required for Chevrolet G30 vehicles.
