Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking efficiency. This design helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent contact with brake pads. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life under various driving conditions.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 17 mm and a discard thickness of 15 mm, ensuring a clear maintenance threshold. The rotor’s 285 mm outside diameter and 46.5 mm height are tailored for precise fitment on specified Subaru models. The 5 bolt holes, each 13 mm in diameter, align with a 114.3 mm bolt circle diameter, matching factory specifications. The directional slotted and drilled surface improves heat dissipation and braking response, while the plain disc finish and zinc silver hat finish provide durability and corrosion resistance.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner operation
• Maintains consistent braking performance under high heat conditions
• Prevents rust and corrosion on the rotor hat for longer service life

Installation Notes and Tips

Ensure the rotor is installed on compatible Subaru Crosstrek, Forester, or Impreza models matching the part number 631-13046L. Verify bolt hole alignment and torque specifications according to manufacturer guidelines. It is recommended to inspect brake pads and hardware during installation to maintain optimal braking system performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function. The rust-resistant coating and precise machining contribute to reliable performance and durability. Warranty information should be confirmed with the original product documentation or supplier.
