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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with both drilled holes and slots to improve water and gas evacuation during braking. This combination helps maintain consistent brake pad contact and reduces brake fade. The zinc silver hat finish provides corrosion resistance, extending rotor life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking efficiency under heavy use. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, ensuring a clear service limit for safety. The rotor measures 365 mm in outside diameter and 45.1 mm in height, fitting precisely on Cadillac CTS and STS models. The 6 bolt holes, each 14.2 mm in diameter, are arranged on a 115 mm bolt circle diameter, matching factory specifications. The directional slotted and drilled surface enhances braking performance by channeling away debris and heat.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Cadillac CTS and STS
• Improves braking response and reduces brake fade during aggressive driving
• Helps prevent rust and corrosion with rust-resistant coating
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances heat dissipation to reduce brake pad glazing

Installation Notes and Tips

Ensure the rotor surface is clean and free of contaminants before installation. Verify the rotor thickness is within the nominal range and replace if below discard thickness. Use proper torque specifications for the 6 lug bolts to avoid rotor warping. This rotor is directional; install with the correct orientation to maintain optimal performance. No additional hardware is included, so use existing or manufacturer-recommended components.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The zinc silver hat finish and rust-resistant coating provide extended durability. While no specific warranty information is provided, adherence to OEM specifications ensures reliable performance for Cadillac CTS and STS vehicles when using part number 631-46016L.
