Detailed Product Features and Specifications

This Dynamite Friction rotor is constructed with a vented design to allow air to flow between the rotor surfaces, reducing heat buildup during braking. The surface is both drilled and slotted, which helps to evacuate gases, dust, and water, improving braking consistency and reducing the risk of brake fade. The rotor's directional surface pattern is optimized for the Acura NSX, ensuring proper rotation and performance.

The rotor's nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life. The 5-lug bolt pattern with a 114.3 mm bolt circle diameter and 12.5 mm bolt hole diameter matches the Acura NSX specifications for a secure fit.

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

The DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This line is designed to offer enhanced braking performance through improved heat dissipation and surface cleaning, making it suitable for performance-oriented vehicles like the Acura NSX. The silver zinc coating on the rotor hat adds durability against rust without compromising the rotor's structural integrity.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or high-speed stops
