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

Brembo is a name synonymous with high-performance braking systems, and their GT Big Brake Kits are a testament to that reputation. This rear kit is designed for the Audi S4 models from 2004-2008 and A4 models from 2006-2008, offering a significant upgrade over the factory setup. It's built for drivers who demand more from their braking system, whether on the street or the track.

At the heart of this kit are the 4-piston calipers, which provide increased clamping force for more consistent stopping power. These calipers work with 345x28mm two-piece rotors. The rotors are drilled, which helps to dissipate heat and reduce the risk of cracking under heavy use. The two-piece design allows for better thermal management and can make rotor replacement simpler down the line. The calipers themselves are cast, offering a solid foundation for the braking components. This kit is a comprehensive solution for improving your vehicle's rear braking performance.

When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide for specific details. While this kit is designed to be a direct fit for the specified Audi models, ensuring proper setup is key to achieving optimal performance and safety. This kit focuses on the rear axle, so consider how it complements your front braking setup for a balanced system.
