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 on the braking surface. This design helps to evacuate gases, dust, and water more effectively than plain rotors, contributing to consistent brake pad contact and improved stopping power. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat generated during braking. The rotor's directional surface pattern is engineered to optimize braking performance by channeling gases and debris away from the pad contact area. With a 5-lug bolt pattern and a bolt circle diameter of 114.3 mm, it fits securely on compatible Mazda models. The rotor's nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The center hole diameter measures 72 mm, and the stud/lug hole diameter is 13.7 mm.

Applications and Problem Solving

• Replaces worn or warped rotors on Mazda 3, Mazda 3 Sport, and Mazda 5
• Improves heat dissipation to reduce brake fade during heavy use
• Helps prevent brake pad glazing by maintaining cleaner pad surfaces
• Reduces rust and corrosion on rotor hats for longer durability
• Enhances braking consistency in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Mazda 3, Mazda 3 Sport, or Mazda 5 models with a 5-lug wheel configuration and 114.3 mm bolt circle diameter. Verify rotor thickness before installation; replace if below the discard thickness of 23 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Proper torque specifications should be followed for lug nuts to avoid rotor warping.
