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 slots in a directional pattern. This design improves brake pad bite and helps evacuate gases and debris, which can reduce brake fade. The zinc silver coating on the rotor hat provides corrosion resistance, extending rotor life especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor features a plain disc finish with a zinc silver hat finish that resists rust. The rotor’s nominal thickness is 16 mm, with a discard thickness of 14 mm, ensuring clear service limits for safety. The rotor measures 308 mm in outside diameter and 47.26 mm in height, fitting precisely on Infiniti QX50 and QX55 vehicles. It includes five bolt holes arranged on a 114.3 mm bolt circle diameter and a center hole diameter of 68 mm, matching OEM specifications for secure mounting.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Infiniti QX50 and QX55
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance under varied driving conditions
• Addresses rotor corrosion issues with rust resistant coating
• Supports directional braking systems with slotted and drilled surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 14 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Confirm bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit and function. The rust resistant zinc silver coating helps extend rotor life in corrosive environments. While no specific warranty information is provided, adherence to discard thickness and proper installation ensures safe and reliable braking performance.
