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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature both drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently than plain rotors, improving braking consistency under demanding conditions. The black zinc coating on the rotor hat provides additional protection against rust, extending the rotor's service life. This product line is tailored for drivers seeking reliable, performance-oriented rotors for their vehicles.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively during braking. The rotor's directional surface pattern, combining drilled holes and slots, enhances pad bite and helps maintain clean contact surfaces. The rotor measures 301 mm in outside diameter with a height of 44.2 mm, fitting precisely on the Mazda RX-8's 5-lug wheel hub with a 114.3 mm bolt circle diameter. The nominal thickness is 18.2 mm, with a discard thickness of 16 mm, ensuring safe replacement intervals. The zinc black finish on the hat section offers rust resistance, which is critical for maintaining rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda RX-8
• Improves heat dissipation to reduce brake fade during spirited driving
• Helps prevent brake pad glazing by maintaining a clean rotor surface
• Addresses corrosion issues with rust-resistant coating
• Enhances braking performance in wet conditions by channeling water away

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 16 mm to maintain safety standards. Use proper torque specifications for the 5 lug bolts with a 114.3 mm bolt circle diameter. The directional drilled and slotted surface requires correct orientation during installation to function as intended. It is recommended to replace brake pads simultaneously to optimize braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-80044L rotor to meet or exceed OEM specifications for the Mazda RX-8.
