Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with both drilled holes and slots on the braking surface. This combination helps to evacuate gases, dust, and water more efficiently than plain rotors, contributing to improved braking consistency. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor faces to dissipate heat generated during braking. The rotor's nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor features a directional surface pattern with both drilled holes and slots, which helps reduce brake fade and improve wet-weather braking. The rotor hat is finished in zinc silver with a rust-resistant coating to protect against corrosion. It includes five bolt holes and stud/lug holes, each with a diameter of 12.7 mm, arranged on a 114.3 mm bolt circle diameter, ensuring proper fitment on Acura NSX models.

Applications and Problem Solving

• Replacement rotor for worn or warped Acura NSX brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Suitable for drivers seeking enhanced brake surface cooling and durability

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 26 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify bolt hole alignment with the Acura NSX hub using the 114.3 mm bolt circle diameter and 12.7 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-58011L rotor to meet OEM specifications for the Acura NSX. The rust-resistant zinc silver finish and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, the rotor is designed for reliable service life when installed and maintained according to manufacturer guidelines.
