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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade under demanding conditions by allowing gases and debris to escape more efficiently. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving environments.

Technical Specifications and Features

This rotor features a solid disc construction with a directional surface pattern, meaning the drilled and slotted design is optimized for rotation in a specific direction to maximize braking efficiency. The rotor's nominal thickness is 10 mm, with a discard thickness of 8 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor includes five bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 65 mm, ensuring proper fitment on compatible Audi and Volkswagen models.

Applications and Problem Solving

• Replaces worn or warped rotors on Audi A3 and Volkswagen Golf models
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant zinc silver coating
• Enhances brake pad bite with drilled and slotted surface design

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 bolt hole alignment with the 5-lug pattern and 112 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 8 mm. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor with rust-resistant coatings and precise machining to meet OEM standards. While specific warranty details are not provided, the rotor's design and materials support durability and consistent braking performance for Audi and Volkswagen vehicles.
