Brembo 04-08 S4/06-08 A4 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Silver

The 345x28mm two-piece rotors in this Brembo GT Big Brake Kit are a key component for improved braking performance. This kit is specifically designed for the rear of your 2004-2008 Audi S4 and 2006-2008 Audi A4, offering a substantial upgrade over the factory setup.

At the heart of this kit are the four-piston cast aluminum calipers, which provide more clamping force and better heat dissipation than smaller, single-piston calipers. The two-piece rotor design, with its floating hat, allows for thermal expansion without inducing rotor distortion, helping to maintain consistent braking performance even under heavy use. The drilled surface on these rotors helps to vent gases and heat away from the pad surface, further enhancing stopping power and reducing fade during spirited driving or track use. This well-built kit aims to provide a noticeable improvement in your vehicle's ability to slow down quickly and reliably.

When installing a big brake kit like this, it's important to ensure you have the correct tools and refer to the manufacturer's installation instructions. While this kit is designed for a direct fit on the specified Audi models, it's always a good idea to confirm compatibility with your specific vehicle's wheel size to ensure clearance. This kit is a significant upgrade for drivers looking for enhanced braking performance.
