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 hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the specific braking needs of vehicles like the Pontiac Firebird, offering a balance of durability and performance.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat more effectively 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 rotor has a nominal thickness of 24.89 mm and a discard thickness of 23 mm, ensuring safe replacement intervals. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining structural integrity over time.

Applications and Problem Solving

• Compatible with Pontiac Firebird models requiring vented, drilled, and slotted rotors
• Helps reduce brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions by evacuating debris
• Prevents premature rotor corrosion with rust-resistant coating
• Maintains consistent braking feel with directional surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. The rotor features 5 bolt holes with an 11.6 mm diameter and a bolt circle diameter of 120.7 mm, matching the Pontiac Firebird specifications. Proper torque specifications should be followed when mounting the rotor to avoid warping. The directional surface requires installation in the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the product is designed to maintain performance and safety throughout its service life when installed and maintained properly.
