Detailed Product Features and Specifications

The 631-80036R rotor from Dynamite Friction is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on delivering rotors with enhanced surface treatments and structural design. The rotor’s vented construction allows air to flow between the rotor faces, helping to dissipate heat more effectively during braking. The drilled and slotted surface is directional, which means it is designed to rotate in a specific direction to optimize debris removal and water dispersion, improving braking consistency in various conditions.

The rotor’s hat is finished in zinc silver, providing a protective layer against rust and corrosion, which extends the rotor’s service life. With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor meets strict wear standards to ensure safety and performance. The rotor includes four bolt holes with a 100 mm bolt circle diameter, making it a direct fit for the Mazda Miata’s brake assembly.

Applications and Problem Solving

• Replaces worn or warped rotors on Mazda Miata models
• Addresses brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions with slotted and drilled design
• Prevents rust and corrosion on rotor surfaces for longer durability
• Restores proper rotor thickness to maintain braking efficiency

Installation Notes and Tips

When installing the Dynamite Friction 631-80036R rotor, ensure the rotor is mounted with the directional surface rotating correctly according to the vehicle’s forward motion. Verify that the bolt holes align with the hub assembly and torque bolts to manufacturer specifications. It is recommended to inspect brake pads and replace them if worn to maximize the benefits of the drilled and slotted rotor design.
