Details on 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 combine drilled holes and slots on the braking surface to improve water, gas, and dust evacuation. This design helps maintain consistent braking performance under demanding conditions. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life while maintaining a clean appearance.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional drilled and slotted surface improves pad bite and helps prevent brake fade by efficiently removing gases and debris. The rotor has a nominal thickness of 22mm and a discard thickness of 20mm, ensuring safe replacement intervals. The zinc black hat finish and rust-resistant coating protect against corrosion, which is critical for maintaining rotor integrity over time. The rotor features 4 bolt holes with a 100mm bolt circle diameter and a center hole diameter of 55mm, matching the fitment requirements for the specified vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Fiat 124 Spider and Mazda MX-5 Miata
• Improves heat dissipation to reduce brake fade during spirited driving or heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating and zinc black hat finish
• Enhances brake pad bite and reduces brake noise through slotted and drilled surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the 4-bolt, 100mm bolt circle diameter pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.
