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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to offer enhanced braking efficiency through its vented, drilled, and slotted rotor design. This product line focuses on improved heat management and debris removal, which helps maintain rotor integrity and brake pad contact. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow, reducing heat buildup during braking. The drilled and slotted surface improves water and gas evacuation, which helps prevent brake fade under demanding conditions. The rotor's directional design ensures optimal performance when installed correctly. With a nominal thickness of 26 mm and a discard thickness of 24 mm, this rotor maintains structural integrity while providing a clear wear limit. The 5-bolt hole pattern with a 115 mm bolt circle diameter matches the specifications for Cadillac CTS and STS models, ensuring proper fitment.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Cadillac CTS and STS
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion with zinc silver coated hat finish
• Enhances braking performance in wet conditions with drilled and slotted surface
• Maintains consistent braking feel by reducing gas and debris buildup

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 115 mm bolt circle pattern. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 24 mm. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor with rust-resistant coatings and precise machining to meet OEM standards. While no specific warranty information is provided, the product is designed to meet the durability and performance requirements for Cadillac CTS and STS brake systems.
