Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve braking performance by reducing heat buildup and aiding in gas and dust dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life, while the rust-resistant coating further protects critical surfaces. This product line is tailored for drivers seeking enhanced braking reliability and durability on their Infiniti vehicles.

Product Specifications and Features

This disc brake rotor features a vented design that promotes airflow to reduce heat during braking, which helps maintain consistent stopping power. The drilled and slotted surface is directional, meaning it is designed to rotate in a specific direction to optimize water and debris removal. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary to maintain safety. The zinc silver hat finish and rust-resistant coating protect against corrosion, which is especially beneficial in humid or wet environments. The rotor fits Infiniti models including FX50, M35h, M37, M56, Q50, Q60, Q70, Q70L, and QX70, ensuring compatibility with a range of vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improved heat dissipation to reduce brake fade during heavy use
• Enhanced water and debris evacuation for consistent braking in wet conditions
• Corrosion resistance to extend rotor lifespan in harsh environments
• Restoring braking performance on Infiniti FX50, Q50, and Q70 models

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the rotor thickness meets or exceeds the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Use proper torque specifications for the 5 bolt holes with a 114.3 mm bolt circle diameter to secure the rotor safely. It is recommended to inspect brake pads and hardware during installation for optimal performance.
