Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Black is a vented disc brake rotor designed to improve heat dissipation and reduce brake fade during demanding driving conditions. The rotor measures 300 mm in outside diameter with an overall height of 51.5 mm, ensuring proper fitment and clearance for the specified BMW models. The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, maintaining consistent braking performance.

The rotor features a directional brake surface, which means it is designed to rotate in a specific direction to maximize cooling and braking efficiency. The zinc black hat finish provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 22 mm and a discard thickness of 20.4 mm, this rotor meets OEM specifications for durability and safety.
