Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

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 rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of drivers who require consistent braking performance under various driving conditions, specifically tailored for vehicles like the Scion tC.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, ensuring it meets safety standards for replacement. The rotor’s surface is both drilled and slotted, which helps evacuate gases and debris from the brake pad surface, reducing brake fade. The directional design of the braking surface optimizes water and dust dispersion during operation. The rotor hat is finished in zinc black, providing a rust-resistant coating to protect against corrosion. It features 5 bolt holes with a bolt circle diameter of 114 mm and a center hole diameter of 62 mm, matching the Scion tC’s specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Scion tC
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8.5 mm before installation. Clean the rotor surface to remove any protective oils prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114 mm bolt circle diameter on the Scion tC. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-91000L rotor to meet industry standards for durability and performance. The rust-resistant zinc black coating on the rotor hat enhances longevity by protecting against corrosion. While no specific warranty information is provided, this rotor is designed to comply with OEM fitment and quality requirements for the Scion tC.
