DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The black zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented vehicles like the Subaru WRX and WRX STI, offering reliable braking under aggressive driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The directional slotted and drilled surface improves water and debris evacuation, maintaining consistent braking performance in various conditions. The rotor measures 326 mm in outside diameter and 63.4 mm in height, fitting precisely on Subaru WRX and WRX STI models. The zinc black hat finish provides rust resistance, protecting the rotor’s core structure.

Applications and Problem Solving

• Improves braking performance for Subaru WRX and WRX STI vehicles
• Reduces brake fade during high-performance or spirited driving
• Helps prevent rotor warping caused by excessive heat buildup
• Enhances water and debris evacuation for consistent braking in wet conditions
• Protects against rust and corrosion with zinc black coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug, 114.3 mm bolt circle diameter pattern on your Subaru WRX or WRX STI. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the rotation arrow pointing in the correct direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-13042L rotor to meet strict quality standards for durability and performance. The rust-resistant zinc black coating on the hat area extends the rotor’s service life. While no specific warranty information is provided, Dynamite Friction products are engineered to comply with OEM fitment and performance requirements for Subaru WRX and WRX STI models.
