About 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 improve braking efficiency. This design helps reduce brake fade by allowing heat and gases to escape more effectively during heavy braking. The silver zinc coating on the rotor hat provides corrosion resistance, making it suitable for long-term use in various driving conditions.

Technical Details and Specifications

This solid disc brake rotor features a nominal thickness of 10.1 mm and a discard thickness of 8 mm, ensuring a reliable service life before replacement is necessary. The rotor’s surface is both drilled and slotted, which enhances braking performance by improving pad bite and reducing heat buildup. The zinc silver finish on the hat section protects against rust, maintaining structural integrity over time. With five bolt holes and a bolt circle diameter of 114.3 mm, this rotor is designed to fit securely on compatible Ford and Mazda vehicles.

Applications and Problem Solving

• Compatible with Ford Probe, Mazda 626, and Mazda MX-6 models requiring a 259 mm diameter rotor
• Addresses brake fade caused by excessive heat during aggressive driving or towing
• Helps reduce brake noise and vibration through slotted and drilled surface design
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent braking performance under varied driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8 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. Directional rotors must be installed following the rotation direction indicated on the rotor surface for optimal performance.
