Brembo 04-08 S4 (B6/B7)/06-08 A4 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Red

This Brembo GT Big Brake Kit for the rear of your 2004-2008 Audi S4 (B6/B7 chassis) or 2006-2008 Audi A4 gives you a significant upgrade over the stock braking system. You'll receive a complete package designed to enhance your car's stopping power and heat management. This kit includes a pair of Brembo's robust 4-piston GT calipers, which are known for their solid construction and consistent performance under demanding conditions. Paired with these calipers are 345x28mm two-piece rotors that feature a drilled surface pattern, helping to dissipate heat and gasses more effectively than solid rotors.

The two-piece rotor design is a notable feature, allowing for better thermal management as the aluminum hat can expand and contract independently of the iron braking surface. This helps reduce the risk of rotor warping and contributes to a more stable pedal feel. The drilled pattern on the rotors is specifically chosen to help clear out brake dust and heat, which is crucial for maintaining optimal braking performance, especially during spirited driving or repeated hard stops. Brembo calipers are built with precision in mind, ensuring smooth operation of the pistons and a firm pedal feel.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is designed to be a direct fit for the specified Audi models, but always consult the included documentation for precise installation procedures. Upgrading your rear brakes with a high-performance kit from Brembo means you're investing in a well-built system that can handle increased thermal loads and provide improved stopping distances.
