Brembo 04-08 S4/06-08 A4 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type3-Silver

If you're looking to significantly upgrade the stopping power on your 2004-2008 Audi S4 or 2006-2008 A4, this Brembo Rear GT Big Brake Kit is a serious consideration. This kit replaces your factory rear brake setup with a much more robust system designed for demanding use, offering improved fade resistance and consistent performance when you need it most.

At the heart of this kit are the Brembo 4-piston cast aluminum calipers, which offer greater clamping force and better heat dissipation than stock calipers. They work in conjunction with the 2-piece, 345x28mm slotted rotors. The two-piece design helps manage heat and reduce weight, while the slots on the rotor surface help to sweep away dust and gas, keeping the pad surface clean for optimal contact. This specific kit features Brembo's Type III slots, known for their aggressive look and effective performance. The calipers come finished in a silver powder coat for a clean, performance-oriented look.

This kit is designed as a direct replacement for the rear axle, though it's always recommended to consult the included installation instructions for specific details and any required hardware. Upgrading your rear brakes to this level ensures a more balanced braking system, especially if you've already upgraded your front brakes. It's a substantial improvement for drivers who push their vehicles hard or frequently carry heavy loads.
