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 improve brake pad bite and reduce heat buildup. The silver zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of daily driving and moderate performance needs, making it suitable for Ford Focus owners seeking a balance of durability and braking consistency.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking response. The rotor measures 350 mm in outside diameter and has a height of 49.4 mm. It features a nominal thickness of 25 mm and a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor includes five bolt holes with a diameter of 13.7 mm and a bolt circle diameter of 108 mm, matching the Ford Focus hub specifications. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Focus models
• Improves heat dissipation to reduce brake fade during extended use
• Helps eliminate brake noise caused by glazing or uneven rotor surfaces
• Maintains consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify that the bolt hole pattern and center hole diameter match the vehicle hub specifications. Use proper torque settings on the lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.
