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 brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented vehicles like the Subaru Impreza, offering a balance between durability and effective braking.

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 consistency. The directional surface design ensures the rotor is installed correctly for optimal performance. The rotor’s nominal thickness is 24 mm, with a discard thickness of 22 mm, indicating when replacement is necessary to maintain safety. The zinc silver hat finish and rust-resistant coating protect against corrosion, especially important in harsh weather conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Subaru Impreza models
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps eliminate brake judder caused by uneven rotor surfaces
• Reduces brake dust accumulation for cleaner braking components
• Addresses corrosion issues on rotor hats with protective zinc coating

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify bolt hole alignment with the Subaru Impreza’s hub using the 5-bolt pattern and 100 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 22 mm. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet industry standards for fitment and performance. The rust-resistant coating and zinc silver hat finish contribute to long-term durability.
