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 provide consistent braking performance under demanding conditions. The silver zinc coating on the hat area offers corrosion resistance, extending rotor life. This product line is designed to meet the specific fitment and performance needs of Subaru models, ensuring compatibility and reliable operation.

Product Specifications and Features

This rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, indicating when replacement is necessary. The 286 mm outside diameter and 63.6 mm height fit the brake system requirements of Subaru BRZ, Forester, Impreza, Legacy, Outback, and WRX models. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to reduce brake fade by improving heat dissipation and removing brake dust and gases. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time. The rotor features 5 bolt holes with a 13 mm diameter and a 100 mm bolt circle diameter, matching the stud/lug hole pattern of the specified Subaru vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Subaru BRZ, Forester, Impreza, Legacy, Outback, and WRX
• Improves braking consistency by reducing heat buildup and brake fade
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion-related rotor damage
• Suitable for drivers seeking enhanced brake pad bite and dust removal

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (8.5 mm) before installation
• Clean rotor surface to remove any protective coating before mounting
• Verify bolt hole alignment with vehicle hub (5 holes, 13 mm diameter, 100 mm bolt circle)
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and calipers during installation for optimal performance
