About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This product line is designed to reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, helping maintain rotor integrity over time.

Detailed Product Description

This disc brake rotor features a plain disc finish with a zinc silver coated hat to resist rust and corrosion. The rotor’s directional slotted and drilled surface is engineered to channel gases, dust, and heat away from the braking surface, which helps maintain optimal braking efficiency. With a nominal thickness of 16 mm and a discard thickness of 14 mm, this rotor meets precise wear specifications to ensure safety and performance. The 5-lug bolt pattern and 114.3 mm bolt circle diameter make it compatible with various INFINITI, Mitsubishi, and Nissan models including the INFINITI QX60, Nissan Pathfinder, and Mitsubishi Outlander PHEV.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response with directional slotted and drilled design
• Resists rust and corrosion for longer service life
• Compatible with specific INFINITI, Mitsubishi, and Nissan models for direct replacement

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the wheel rotation. Verify the bolt hole pattern and center hole diameter match the vehicle specifications. It is recommended to inspect brake pads and hardware during installation to maintain optimal braking system performance. Proper torque specifications should be followed to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and precise machining contribute to consistent braking performance and durability. While no specific warranty information is provided, the product is designed for reliable service on compatible INFINITI, Mitsubishi, and Nissan vehicles.
