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 feature a combination of drilled holes and slots on the braking surface. This design helps to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking performance with enhanced heat dissipation and durability.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal vanes between the rotor faces to improve airflow and cooling. The rotor's nominal thickness is 18 mm, with a discard thickness of 16 mm, indicating when replacement is necessary. The rotor surface is directional, featuring both drilled holes and slots to optimize braking efficiency. The rotor hat is finished in zinc silver to resist rust, and the overall height measures 45 mm. It includes 4 bolt holes with a 100 mm bolt circle diameter, designed to fit the Mazda Miata's hub assembly precisely.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Mazda Miata models
• Improves braking performance under high heat conditions
• Reduces brake fade during aggressive driving or track use
• Helps prevent rust and corrosion on rotor hats
• Enhances water and debris evacuation for consistent braking in wet weather

Installation Notes and Tips

When installing the Dynamite Friction 631-80022L rotor on a Mazda Miata, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the directional surface orientation matches the vehicle’s rotation direction for optimal performance. Torque the bolts to manufacturer specifications and inspect brake pads for wear to maintain balanced braking. It is recommended to replace rotors in pairs to ensure even braking response.
