Details on the DFC Brake Rotor - Drilled and Slotted - Black 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. This design helps maintain consistent braking performance by allowing gases, dust, and water to escape more efficiently. The black zinc 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, which means it has internal vanes between the two braking surfaces to improve airflow and heat dissipation. The rotor's nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor surface is finished plain, while the hat is coated in zinc black for rust resistance. It features a directional surface type with both drilled holes and slots, enhancing braking under wet or high-performance conditions. The rotor includes four bolt holes with a 100 mm bolt circle diameter and a center hole diameter of 55 mm, matching the Mazda Miata's specifications.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves water and debris evacuation for consistent braking in wet conditions
• Helps maintain cooler rotor temperatures to prevent warping
• Provides corrosion resistance to extend rotor lifespan
• Ensures proper fitment and performance for Mazda Miata brake systems

Installation Notes and Tips

When installing the Dynamite Friction 633-80036L rotor on a Mazda Miata, ensure the rotor is mounted with the directional surface facing the correct rotation direction. Verify that the bolt holes align with the vehicle’s hub using the 100 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 22 mm. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust-resistant zinc black coating on the rotor hat helps protect against corrosion, contributing to long-term durability. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure reliable braking performance for Mazda Miata owners.
