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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking efficiency. This design helps reduce brake fade by improving heat dissipation and allows for better removal of brake dust and gases. The zinc black hat finish adds corrosion resistance, extending rotor life especially in harsh environments. This product line is tailored for drivers seeking reliable, vented rotors with directional surfaces for specific vehicle applications.

Product Details and Specifications

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The drilled and slotted surface improves pad bite and helps maintain consistent friction by channeling away water and debris. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The zinc black finish on the hat section provides rust resistance, while the plain disc finish maintains structural integrity. The rotor includes six bolt holes with a bolt circle diameter of 139.7 mm, compatible with the specified Infiniti and Nissan models.

Applications and Problem Solving

• Compatible with Infiniti Armada, QX56, and QX80 models requiring vented disc brake rotors
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces brake dust accumulation and improves pad contact with slotted and drilled design
• Prevents corrosion and extends rotor lifespan with rust-resistant zinc black hat finish
• Maintains braking performance in wet or dusty conditions with directional surface

Installation Notes and Tips

Ensure the rotor is installed on the correct side as indicated by the directional surface markings. Verify that the bolt hole pattern matches the vehicle’s hub assembly (6 bolt holes, 139.7 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 20 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
