Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve water and gas evacuation from the braking surface. This design helps maintain consistent braking performance and reduces brake fade. The black zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life in various driving environments.

Technical Specifications and Features

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, effectively dissipating heat generated during braking. The directional drilled and slotted surface improves pad bite and helps remove debris and moisture, which is critical for maintaining braking efficiency. The rotor’s hat is finished with a zinc black coating, providing rust resistance and a clean appearance. With an outside diameter of 348 mm and a discard thickness of 34.4 mm, this rotor meets OEM specifications for the listed vehicle applications.

• Reduced braking performance in wet conditions from water accumulation
• Vibration or noise caused by warped or damaged rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the rotor thickness is above the discard thickness of 34.4 mm to maintain safe braking performance. Use proper torque specifications for lug nuts and check for any signs of uneven wear or damage on brake pads. It is recommended to replace rotors in pairs to maintain balanced braking.
