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

If you're looking to significantly improve the stopping power and heat management on your 2004-2008 Audi S4 or 2006-2008 Audi A4, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle repeated hard braking, making it ideal for track days or spirited driving where consistent performance is crucial. The larger rotors and multi-piston calipers work together to dissipate heat more effectively than stock components, reducing the risk of brake fade.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer a more rigid structure and better pad engagement compared to smaller calipers. They clamp down on the 345x28mm two-piece rotors, which are slotted with Brembo's Type 3 pattern. These slots help to sweep away dust and gas that can build up between the pad and rotor surface, ensuring a cleaner contact patch and more consistent braking force, especially under heavy load. The two-piece rotor design also helps to reduce weight and manage heat expansion.

This Brembo kit is a comprehensive solution for enhancing your vehicle's braking system. It includes everything needed to install the calipers and rotors, ensuring a direct fit for the specified Audi models. While this is a significant upgrade, it's important to note that a proper bedding-in procedure is essential for optimal performance and longevity of the pads and rotors. Refer to the manufacturer's installation instructions for the recommended bedding process and any specific tool requirements.
