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 combine drilled holes and slots to enhance brake pad bite and reduce heat buildup. This product line is designed to maintain consistent braking performance under demanding conditions, making it suitable for high-performance vehicles like the Audi A8 Quattro and Bentley Continental series. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life.
Technical Specifications and Features
This vented rotor features a directional surface type with both drilled holes and slots, which help to dissipate heat and gases generated during braking. The nominal thickness of 22 mm ensures durability, while the discard thickness of 20 mm indicates when replacement is necessary to maintain safety. The rotor’s 335 mm outside diameter and 42.4 mm overall height are matched precisely to the specified vehicle models. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment on compatible Audi and Bentley vehicles.
Applications and Problem Solving
- Improves braking performance on Audi A8 Quattro and Bentley Continental, Flying Spur, and S8 models
- Reduces brake fade caused by heat buildup during aggressive driving
- Helps prevent rotor warping and cracking through vented design
- Minimizes rust and corrosion with zinc silver coating
- Enhances pad bite and debris removal with drilled and slotted surface
Installation Notes and Tips
Ensure the rotor is installed on vehicles matching the specified fitment: Audi A8 Quattro and Bentley Continental, Flying Spur, and S8. Verify the bolt pattern and rotor dimensions before installation. Directional rotors must be mounted with the correct rotation direction for optimal performance. Inspect brake pads and hardware during installation to maintain overall braking system integrity.
Quality Assurance
Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust-resistant zinc silver finish helps extend rotor life in various driving conditions.
