Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, designed to provide consistent braking performance under demanding conditions. The rotor features a directional surface with both slots and drilled holes, which help to reduce brake fade by improving heat dissipation and allowing gases and debris to escape. The nominal thickness of 11 mm ensures structural integrity, while the discard thickness of 9 mm indicates when replacement is necessary to maintain safe braking performance.

The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rust resistant coating on the rotor surface helps protect against environmental damage, extending the rotor’s service life. With a 330 mm outside diameter and a 5-lug bolt pattern, this rotor is specifically compatible with Acura MDX, Honda Passport, and Honda Pilot models requiring these dimensions.

Applications and Problem Solving

• Replaces worn or warped rotors on Acura MDX, Honda Passport, and Pilot
• Addresses brake fade caused by overheating during heavy braking
• Improves braking response and reduces noise with slotted and drilled design
• Prevents rust and corrosion for longer rotor lifespan
• Maintains proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor is installed on vehicles with matching bolt pattern and dimensions. Verify the discard thickness before installation to confirm the rotor is within safe limits. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed for the 5 bolt holes to ensure secure fitment. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet industry standards for durability and performance. The rust resistant coating and Geospec silver grey hat finish contribute to corrosion resistance. While specific warranty details are not provided, this rotor is designed to maintain consistent braking performance when installed and maintained according to manufacturer guidelines.
