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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the specific braking demands of performance-oriented vehicles like the Cadillac ATS and CT4.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively, reducing the risk of brake fade during extended use. The rotor’s surface is both drilled and slotted, which helps evacuate gases and debris from the brake pad interface, maintaining consistent friction. The rotor’s nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring safe replacement intervals. The 5-lug bolt pattern with a 115 mm bolt circle diameter and 14.2 mm bolt hole diameter matches factory specifications for Cadillac ATS and CT4 models. The zinc silver hat finish offers rust resistance, while the plain disc finish maintains a clean braking surface.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Cadillac ATS and CT4
• Improves heat dissipation to reduce brake fade during aggressive driving
• Drilled and slotted surface helps prevent brake pad glazing and maintains braking consistency
• Rust-resistant coating protects against corrosion in humid or wet environments
• Directional design optimizes braking performance and pad contact

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the vehicle manufacturer. Verify that the bolt hole pattern and dimensions match the vehicle’s hub assembly. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Clean the rotor surface of any protective coatings or oils before installation to prevent brake noise or reduced friction.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-46035R rotor to meet or exceed OEM specifications for Cadillac ATS and CT4 vehicles. The rust-resistant zinc silver finish and vented rotor design contribute to durability and consistent performance. Warranty details should be confirmed with the product supplier or manufacturer, as they may vary.
