Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is a solid rotor designed to meet the braking demands of the Buick Lucerne and Cadillac DTS. The rotor features a plain disc finish with a zinc silver coated hat to resist rust and corrosion, extending the rotor's service life. The drilled and slotted surface type enhances heat dissipation and helps prevent brake fade by allowing gases and debris to escape during braking. The directional brake surface ensures proper alignment for optimal performance.

With a nominal thickness of 12 mm and a discard thickness of 10.5 mm, this rotor maintains structural integrity under heavy braking conditions. The rotor's five bolt holes, each 14.3 mm in diameter, fit securely on a 115 mm bolt circle diameter, matching the factory specifications for the Buick Lucerne and Cadillac DTS. The center hole diameter of 70.7 mm ensures proper hub fitment.
