Detailed Product Description

This DFC Brake Rotor from Dynamite Friction features a drilled and slotted surface designed to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The directional pattern optimizes performance by channeling debris and water away from the contact surface. The rotor’s hat is finished in zinc black, providing a durable rust-resistant coating that helps maintain structural integrity over time. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, this rotor meets strict specifications to ensure safe and reliable braking. The 5-lug bolt pattern with a 112 mm bolt circle diameter and 16.7 mm bolt hole diameter ensures compatibility with specific BMW and Mini models.
