Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. This rotor features a plain disc finish with a zinc silver hat finish that provides corrosion resistance, extending rotor life. The vented design further supports cooling during heavy braking conditions, making it suitable for daily driving and moderate performance needs.

Technical Specifications and Features

This disc brake rotor is vented and directional, with a surface type that is both slotted and drilled to enhance braking efficiency. It has a nominal thickness of 25 mm and a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor includes five bolt holes with a diameter of 13.8 mm and a bolt circle diameter of 108 mm, matching the stud/lug hole pattern for secure fitment. The overall height and height are both 49 mm, with a center hole diameter of 63.6 mm. The zinc silver hat finish and rust-resistant coating help protect against corrosion, maintaining rotor integrity over time.
