Product Description

The EBC GD1422 is a high-performance rear brake rotor set designed for Audi B6 and B7 platform vehicles equipped with sport braking systems. As part of EBC's GD Series, these rotors feature a slotted and dimpled surface designed to improve braking efficiency, heat management, and overall pedal consistency under demanding driving conditions.

The slot design continuously clears brake dust, gases, and moisture from the pad surface, improving bite and maintaining stable braking response. The dimpled surface helps reduce heat stress points compared to fully drilled rotors, lowering the risk of cracking while still supporting efficient thermal dissipation.

Manufactured from OE-grade grey cast iron with a corrosion-resistant coating, the GD1422 is built for durability and long service life. It is intended as a direct upgrade for factory rear sport brake setups and must be matched with the correct 300mm rear rotor configuration for proper fitment and safety.
