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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that feature a combination of drilled holes and slots on the braking surface. This design improves heat dissipation and helps reduce brake fade during demanding driving conditions. The zinc silver hat finish and rust-resistant coating extend the rotor’s service life by protecting against corrosion, making it suitable for vehicles like the Cadillac Corvette and Chevrolet XLR that require reliable braking components.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and cooling, which is critical for maintaining braking efficiency under heavy use. The rotor’s nominal thickness is 32 mm, with a discard thickness of 30 mm, indicating when replacement is necessary to maintain safety. The drilled and slotted surface is directional, designed to channel gases and debris away from the pad surface, improving contact and braking response. The rotor fits vehicles with a 5-lug bolt pattern, 13.4 mm bolt hole diameter, and a bolt circle diameter of 120.7 mm, matching the specifications for Cadillac Corvette and Chevrolet XLR models.

Applications and Problem Solving

• Replaces worn or warped rotors on Cadillac Corvette and Chevrolet XLR
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps prevent rust and corrosion with zinc silver hat finish and coating
• Enhances braking performance with directional drilled and slotted surface
• Maintains proper rotor thickness for safe and consistent braking

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 32 mm and is above the discard thickness of 30 mm. The rotor is designed for a 5-lug bolt pattern with 13.4 mm bolt holes and a 120.7 mm bolt circle diameter, so verify compatibility with your vehicle’s hub assembly. Directional rotors must be installed with the correct rotation direction to maintain optimal performance. Clean the rotor surface before installation to remove any protective coatings or debris.

Quality Assurance

Dynamite Friction manufactures the 631-46018R rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to long-term reliability. While no specific warranty information is provided, the rotor is designed to meet OEM specifications for Cadillac Corvette and Chevrolet XLR models, ensuring consistent braking quality.
