Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a vented construction to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall braking efficiency. The directional surface design ensures the rotor is installed correctly for optimal performance.

The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when replacement is necessary to maintain safety and performance. The hat section features a zinc silver rust-resistant coating to protect against corrosion, extending the rotor’s service life. The rotor includes six bolt holes with a 103 mm bolt circle diameter and stud/lug hole diameter of 10.6 mm, matching the factory specifications for Nissan 720, D21, and Pickup vehicles.

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

The DFC Brake Rotor - Drilled and Slotted - Silver product line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This line is designed to provide reliable braking performance under demanding conditions, with features that help maintain rotor integrity and braking consistency over time.
