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 helps to reduce brake fade by improving heat dissipation and gas evacuation during braking. The black zinc finish on the rotor hat provides corrosion resistance, while the solid rotor construction ensures consistent braking performance. This product line is tailored for drivers seeking reliable stopping power with enhanced rotor durability.

Technical Specifications and Features

This rotor is a solid disc type with a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring a clear service limit for safe operation. The rotor's surface is both drilled and slotted in a directional pattern, which aids in channeling away brake dust and gases, improving pad bite and overall braking efficiency. The rotor hat is finished in zinc black, providing rust resistance along with a protective coating on the entire rotor surface. It features 5 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 71.7 mm, matching the specifications required for Mazda 3 and Mazda 3 Sport models. The overall diameter measures 280 mm with a height of 40.9 mm.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Mazda 3 and Mazda 3 Sport
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps eliminate brake noise caused by glazing or uneven rotor surfaces
• Addresses rust and corrosion issues with rust resistant coating
• Enhances braking response with directional drilled and slotted design

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 residue before mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter for proper fitment on Mazda 3 and Mazda 3 Sport models. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and zinc black hat finish contribute to long-term durability. While no specific warranty information is provided, the product is designed for reliable performance and consistent braking under normal operating conditions.
