Detailed Product Description
This DFC Geoperformance Rotor - Drilled and Slotted is designed to meet the braking demands of Audi models such as the A8 Quattro, e-tron S Sportback, and S7 Sportback. The rotor features a directional surface with both drilled holes and slots, which help to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The rotor’s nominal thickness of 28 mm ensures a substantial braking surface, while the discard thickness of 26 mm indicates when replacement is necessary to maintain safety and performance.
The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance along with a rust resistant coating on the disc surface to extend service life. With a 5-bolt hole pattern and a bolt circle diameter of 112 mm, this rotor is compatible with a range of Audi Quattro models, including the SQ7 and Q8 e-tron variants.
Applications and Problem Solving
- Reduces brake fade during aggressive or prolonged braking
- Improves heat dissipation to prevent rotor warping
- Helps maintain consistent braking performance under heavy loads
- Resists rust and corrosion for longer rotor life
- Compatible with multiple Audi Quattro models requiring 350 mm rotors
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 26 mm before installation. The directional drilled and slotted surface must be installed following the correct rotation direction for optimal performance. Verify the 5-lug bolt pattern and 112 mm bolt circle diameter match your vehicle specifications. Clean the rotor surface before installation to remove any protective coatings or residues.
