About the DFC Brake Rotor - Drilled and Slotted - Silver Line

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 heat dissipation. This design helps reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life.

Detailed Product Description

This solid disc brake rotor features a drilled and slotted surface type, which aids in venting gases and debris away from the brake pad surface. The directional design ensures that the rotor is installed correctly to maximize braking efficiency. With a nominal thickness of 11.6 mm and a discard thickness of 10 mm, the rotor maintains structural integrity while providing reliable stopping power. The zinc silver hat finish offers protection against rust, making it suitable for various driving environments. The rotor’s five bolt holes and 112 mm bolt circle diameter ensure compatibility with the specified Audi and Volkswagen models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A3 and Volkswagen Golf, Jetta, Bora, and Jetta City
• Improves braking response and reduces brake fade during heavy use
• Helps eliminate brake noise caused by uneven rotor surfaces
• Addresses rust and corrosion issues on rotor hats for longer service life
• Enhances heat dissipation to prevent premature brake pad wear

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify that the bolt hole pattern matches the vehicle’s hub assembly (5 bolts, 112 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 10 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.
