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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with a corrosion-resistant black zinc finish on the hat. This product line is designed to provide consistent braking performance under demanding conditions, particularly for performance-oriented vehicles like the Subaru WRX and WRX STI. The directional design optimizes rotor surface contact and helps channel gases and debris away from the brake pad interface.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and reduce heat buildup during braking, which helps maintain braking efficiency and rotor longevity. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28 mm, ensuring a clear maintenance threshold. The rotor features five bolt holes with a diameter of 12.8 mm and a bolt circle diameter of 114.3 mm, matching the Subaru WRX and WRX STI hub specifications. The zinc black finish on the hat provides rust resistance, extending the rotor’s service life in various driving conditions.

Applications and Problem Solving

• Replacement rotor for worn or warped Subaru WRX and WRX STI brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Slotted and drilled surface helps remove brake dust and gases for consistent braking
• Rust-resistant coating prevents corrosion in wet or salty environments
• Directional design enhances braking performance and pad contact

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern and center hole diameter match the vehicle hub before installation. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance.
