Product Line Details: DFC Geoperformance Rotor - Drilled and Slotted

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that feature a directional surface combining drilled holes and slots. This design aids in heat dissipation and gas evacuation during braking, which helps maintain consistent stopping power and reduces brake fade. The Geospec silver grey hat finish not only provides corrosion resistance but also adds a durable protective layer to extend rotor life.

Technical Description and Specifications

This disc brake rotor is manufactured with a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring a reliable service life before replacement is necessary. The rotor’s 330 mm outside diameter and 39 mm height are optimized for the braking systems of Acura MDX, Honda Passport, and Honda Pilot models. The directional slotted and drilled surface improves water and debris clearance, enhancing braking performance in various driving conditions. The rotor includes a rust-resistant coating and a Geospec silver grey hat finish to protect against corrosion and wear. The 5 bolt holes with a 14.6 mm diameter and a 120 mm bolt circle diameter match the factory specifications for secure fitment.

Applications and Problem Solving

• Compatible with Acura MDX, Honda Passport, and Honda Pilot for direct replacement
• Helps reduce brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response in wet or debris-prone environments
• Protects against rust and corrosion for longer rotor life

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 9 mm. The directional slotted and drilled surface requires correct orientation during installation to maintain optimal performance. Verify the 5-lug bolt pattern and 120 mm bolt circle diameter match the vehicle specifications. Clean the rotor surface before mounting to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor damage.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards. The rust-resistant coating and Geospec silver grey finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the product is designed to meet the performance and safety requirements for Acura MDX, Honda Passport, and Honda Pilot vehicles.
