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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking performance by enhancing heat dissipation and reducing brake fade. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the specifications required for various compact and subcompact vehicles, including the Hyundai Accent and Kia Rio, ensuring compatibility and reliable braking under normal driving conditions.

Technical Description and Specifications

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking. The drilled and slotted surface improves water and debris removal from the rotor face, which is especially beneficial in wet or dusty environments. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor’s bolt pattern includes four 12.5 mm diameter holes arranged on a 100 mm bolt circle diameter, matching the fitment requirements for compatible vehicles. The zinc silver hat finish provides rust resistance, helping to maintain structural integrity over time.

Compatible Vehicles and Applications
