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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the hat area provides enhanced rust resistance, extending rotor life. This product line is designed to meet the demands of drivers who require consistent braking performance on Ford and Lincoln vehicles such as the Aviator, Explorer, and Mustang.

Technical Description and Features

This disc brake rotor features a directional surface with both drilled holes and slots, which aid in venting gases and debris from the brake pad surface. The rotor’s 350 mm outside diameter and 26 mm nominal thickness provide a robust braking surface, while the discard thickness of 24.5 mm indicates the minimum safe thickness before replacement is necessary. The zinc silver hat finish and rust resistant coating help protect against corrosion, especially in harsh weather conditions. The rotor includes five bolt holes with a diameter of 15.7 mm and a bolt circle diameter of 114.3 mm, ensuring proper fitment and secure mounting on compatible vehicles.

Compatible Vehicles and Applications

• Replacement rotor for Ford Aviator models requiring a 350 mm drilled and slotted rotor
• Suitable for Ford Explorer vehicles needing enhanced heat dissipation and corrosion resistance
• Compatible with Ford Mustang models designed for 5-lug bolt patterns with 114.3 mm bolt circle diameter
