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 and gas dissipation during braking. The black zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life while maintaining a clean appearance.

Product Details and Specifications

This solid disc brake rotor features a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring it meets safety standards for replacement intervals. The rotor's 265 mm outside diameter and 41 mm overall height are designed to match the factory specifications for Mazda 3 and 3 Sport vehicles. The drilled and slotted surface improves water and debris clearance, while the directional design optimizes braking performance by channeling gases away from the contact surface. The zinc black hat finish provides rust resistance, helping maintain rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda 3 and 3 Sport
• Improves braking response and reduces brake fade under heavy use
• Helps prevent rust and corrosion on rotor hats
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Enhances heat dissipation for consistent braking performance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter for proper fitment on Mazda 3 and 3 Sport models. Use proper torque specifications when tightening lug nuts to avoid rotor warping.
