Details on the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking performance by enhancing heat dissipation and reducing brake fade. The silver zinc coating on the rotor hat provides additional rust resistance, making it suitable for vehicles exposed to varying weather conditions. This product line is designed to meet the specifications required by Cadillac and Chevrolet models, ensuring compatibility and reliable operation.

Technical Description and Specifications

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, helping to maintain optimal operating temperatures 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 pad bite and reducing the risk of brake fade. The rotor has a nominal thickness of 30 mm and a discard thickness of 27 mm, indicating when replacement is necessary. The zinc silver hat finish and rust-resistant coating protect against corrosion, extending the rotor’s service life. With a 5-bolt hole pattern and a 120 mm bolt circle diameter, this rotor fits specific Cadillac ATS, CTS, CT6, and Chevrolet Camaro models.

Applications and Problem Solving

• Compatible with Cadillac ATS, CTS, CT6, and Chevrolet Camaro models requiring a 321 mm diameter rotor
• Addresses brake fade caused by excessive heat during aggressive driving or towing
• Improves braking performance in wet conditions by evacuating water from the rotor surface
• Reduces brake dust buildup for cleaner braking components
• Prevents premature rotor corrosion with rust-resistant coatings

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27 mm before installation. The rotor is directional, so proper orientation during installation is critical for optimal performance. Verify the bolt hole pattern matches your vehicle’s specifications (5 holes, 16 mm diameter, 120 mm bolt circle). Clean the rotor surface of any protective coatings or oils before mounting to ensure proper pad contact. It is recommended to replace brake pads when installing new rotors to maintain consistent braking performance.
