Brembo 04-08 S4 (B6/B7) Front GT BBK 6 Piston Cast 355x32 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit is specifically for the 2004-2008 Audi S4 models, known as the B6 and B7 generations. It's a complete front brake upgrade designed to significantly improve stopping power and heat management for your performance sedan. The kit centers around a pair of massive 355x32mm two-piece rotors, which are drilled for better heat dissipation and paired with a robust 6-piston caliper.

Brembo is well-known for its high-performance braking systems, and this GT kit is a prime example. The calipers are cast from a strong aluminum alloy for a good balance of rigidity and light weight, and they house 6 pistons that apply even pressure across the larger rotor surface. This means more consistent braking force, especially under demanding conditions like repeated hard stops or track use. The two-piece rotor design, with its floating hat and separate friction ring, helps to reduce stress and prevent warping under extreme heat. The drilled surface on the rotors helps to vent gases and water away from the pad surface, maintaining optimal friction.

When installing a big brake kit like this, it's important to remember that it's a significant upgrade. You'll want to ensure you have the right tools and potentially some assistance, as these components are larger and heavier than stock. While this kit is designed as a direct replacement for the factory front brake setup, always refer to the manufacturer's installation instructions for specific details and torque specifications. This kit is a substantial investment in your S4's performance and safety, offering a noticeable improvement in braking feel and capability.
