Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize brake pad contact and heat dissipation. This product line is designed to provide consistent braking performance under demanding conditions, making it suitable for Mazda RX-7 owners seeking a balance between durability and enhanced rotor cooling.

Technical Specifications and Features

This disc brake rotor is vented to allow air flow between the rotor surfaces, which helps reduce brake fade during extended use. The rotor’s surface is both drilled and slotted in a directional pattern, improving water and debris evacuation while maintaining pad bite. The rotor has a nominal thickness of 20 mm and a discard thickness of 18 mm, ensuring safe replacement intervals. The zinc silver hat finish offers corrosion resistance, complemented by an overall rust-resistant coating to extend rotor life. The rotor features five bolt holes with a 114.3 mm bolt circle diameter, matching the Mazda RX-7’s hub specifications precisely.

Applications and Problem Solving

• Replaces worn or warped rotors on Mazda RX-7 models
• Improves brake cooling to reduce fade during spirited driving
• Enhances water and debris clearance for consistent braking in wet conditions
• Restores braking performance affected by rotor surface damage
• Provides corrosion resistance to extend rotor service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify bolt hole alignment with the Mazda RX-7 hub using the 114.3 mm bolt circle diameter and five-lug pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the rotation arrow pointing in the correct direction of wheel rotation.

Quality Assurance

Dynamite Friction manufactures the 631-80015R rotor to meet OEM standards for fit and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance and meet the demands of Mazda RX-7 applications.
