Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented design to improve airflow and reduce heat buildup during braking. The rotor’s surface combines drilled holes and slots, which help evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The rotor has a nominal thickness of 28 mm and a discard thickness of 26 mm, ensuring durability and safety over its service life.

The rotor’s outside diameter measures 330 mm, with an overall height of 47.3 mm. It features a zinc silver coating on the hat to resist rust and corrosion, extending the rotor’s lifespan. The plain disc finish complements the drilled and slotted surface, providing a balance between performance and longevity. The rotor is designed with a directional brake surface, which means it must be installed in the correct rotation direction to maximize effectiveness.
