Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors engineered for enhanced heat dissipation and improved braking response. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the zinc silver coating on the rotor hat provides corrosion resistance to extend service life.

Technical Specifications and Features

This rotor features a solid disc design with a 260 mm outside diameter and an overall height of 48.3 mm. The directional slotted and drilled surface improves pad bite and helps maintain consistent braking under demanding conditions. The rotor’s nominal thickness is 11.6 mm, with a discard thickness of 10 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, protecting the rotor’s core components. It includes 5 bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 65 mm, matching factory specifications for the listed Audi and Volkswagen models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Audi A3 and Volkswagen Golf, Jetta, Bora, and Jetta City
• Improves heat dissipation to reduce brake fade during extended braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Restores braking performance compromised by rust or corrosion
• Supports directional braking surface requirements for specific vehicle models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10 mm before installation. Clean the rotor surface and hub mounting area to remove any debris or rust for proper fitment. Use the correct torque specifications for the 5 lug bolts with a 112 mm bolt circle diameter. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the 631-74027R rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and precision machining contribute to long service life and consistent braking. Warranty information is available through the manufacturer and should be consulted for specific coverage details.
