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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction offers rotors with a combination of drilled holes and slots on the braking surface. This design improves heat dissipation and helps reduce brake fade under demanding conditions. The black zinc finish on the rotor hat provides additional protection against rust, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking performance with enhanced durability.

Technical Specifications and Features

This rotor is a solid type, measuring 280 mm in outside diameter and 40.9 mm in overall height. It features a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring clear service limits for safe operation. The rotor surface is both drilled and slotted, arranged directionally to optimize braking efficiency and debris removal. The hat is finished with a black zinc coating to resist corrosion, while the rotor surface has a rust-resistant coating to maintain integrity over time. The rotor includes 5 bolt holes with a bolt circle diameter of 114.3 mm and stud/lug holes sized at 13.7 mm diameter, matching the Mazda 3 and 3 Sport specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Mazda 3 and Mazda 3 Sport
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance under wet conditions by channeling water away
• Addresses rotor corrosion issues with rust-resistant coatings
• Restores proper braking surface for improved pedal feel and stopping power

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 coatings or oils prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to Mazda 3 and 3 Sport models. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors should be installed with the rotation arrow pointing in the correct direction of wheel rotation.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mazda 3 and Mazda 3 Sport vehicles. The rust-resistant coatings and zinc black hat finish contribute to long-term durability. While no specific warranty information is provided, the rotor is designed to maintain performance within the specified thickness limits and service parameters.
