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 on the braking surface. This design aids in reducing brake fade by allowing gases and debris to escape, while the vented rotor construction improves airflow to maintain optimal operating temperatures. The zinc silver hat finish provides corrosion resistance, extending rotor life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented and directional, featuring a slotted and drilled surface type that supports effective heat dissipation and debris removal. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor’s outside diameter measures 290 mm with an overall height of 45 mm. It includes five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 72 mm, matching the Mazda MX-5 Miata’s specifications. The zinc silver hat finish and rust-resistant coating help protect against corrosion and wear.

Applications and Problem Solving

• Improves braking performance for Mazda MX-5 Miata vehicles
• Reduces brake fade during aggressive or prolonged braking
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes brake dust and debris accumulation on the rotor surface
• Extends rotor lifespan with rust-resistant coating and zinc silver finish

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or contaminants prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to the Mazda MX-5 Miata. Proper torque specifications should be followed to avoid rotor distortion. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-80047R rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to corrosion protection. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and consistent braking under normal operating conditions.
