Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The rotor surface is both drilled and slotted, which assists in channeling away gases, dust, and water, maintaining consistent brake pad contact. The directional brake surface ensures optimal performance when installed correctly according to the rotation direction.

The rotor features a plain disc finish combined with a zinc silver coating on the hat to resist rust and corrosion, extending the rotor's service life. With a nominal thickness of 26 mm and a discard thickness of 24.5 mm, this rotor meets the necessary specifications for safe and effective braking. The five bolt holes and stud/lug holes, each 13.7 mm in diameter, fit securely on the 114.3 mm bolt circle diameter hub, ensuring proper fitment on compatible vehicles.
