EBC Brakes GD Sport Dimpled and Slotted Rear Brake Rotors for 2004-2008 Audi S4 (GD1422)

Fits 2004-2008 Audi S4 Avant, Base, and Cabriolet models.

EBC Brakes GD Sport rotors are designed for high-performance applications where heat management and pad degassing are critical. These rotors are cast from OE-spec grey iron and feature a unique dimpled and slotted pattern. The wide-aperture slots draw cool air into the braking zone to reduce brake fade at high speeds or under heavy loads, while effectively clearing dust, dirt, and gases from the contact patch. Unlike traditional cross-drilled rotors, the blind-drilled dimples provide an exit point for pad vapors without compromising the structural integrity of the rotor or inviting stress cracks.

• Precision Machined: Manufactured from high-quality grey cast iron tested for tensile strength, grain structure, and hardness.
• Enhanced Cooling: Wide slots help brakes run cooler, significantly reducing fade during spirited driving or towing.
• Dimpled Design: Prevents pad outgassing while maintaining rotor strength to avoid crack formation.
• Import Specific Finish: Features a gold anodized protective coating to prevent corrosion in the non-frictional zones.
• Direct Replacement: Engineered to bolt directly to factory mounting points as a performance upgrade over stock rear rotors.
