Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced surface designs to improve braking efficiency and rotor longevity. The drilled and slotted surface helps to reduce brake fade by allowing gases and debris to escape, while the directional pattern supports consistent pad contact and heat management. The rotor is solid rather than vented, providing a robust structure suitable for standard braking applications on the Acura MDX.

The rotor features a plain disc finish combined with a zinc silver coating on the hat to resist rust and corrosion, extending the rotor's service life. With a nominal thickness of 11 mm and a discard thickness of 9 mm, this rotor meets precise wear specifications to ensure safe replacement intervals. The 5-lug bolt pattern with 12.7 mm diameter holes and a 114.3 mm bolt circle diameter matches the Acura MDX's factory specifications for a direct fit.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Acura MDX
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Restores braking performance affected by rust or corrosion on original rotors
• Supports consistent brake pad contact for smoother stopping power

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify the 5-lug bolt pattern and 114.3 mm bolt circle diameter match your Acura MDX specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal braking performance.
