Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking efficiency. This design helps evacuate gases, dust, and water from the rotor surface, maintaining consistent contact with brake pads. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor’s surface is finished plain, while the hat features a zinc silver coating to resist corrosion. The rotor includes five bolt holes with a 114.3 mm bolt circle diameter and a center hole diameter of 68 mm, matching the factory specifications for the compatible Mazda models.

Applications and Problem Solving

• Replaces worn or warped rotors on Mazda 3, 3 Sport, and CX-3 vehicles
• Improves braking performance by reducing brake fade under heavy use
• Helps prevent rust and corrosion on rotor hats for longer durability
• Enhances heat dissipation to maintain consistent braking response
• Reduces brake dust and gas buildup for cleaner braking surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 114.3 mm bolt circle diameter and 5-lug pattern. Proper torque specifications should be followed to avoid rotor warping. This rotor is directional; install with the correct orientation to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mazda 3, 3 Sport, and CX-3 models. The rust-resistant zinc silver hat finish adds durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable braking performance when installed and maintained according to manufacturer guidelines.
