Brembo 08-17 S5/09-16 S4 Front GT BBK 6 Piston Cast 380x32 2pc Rotor Slotted Type3-Black

This Brembo GT Big Brake Kit for your 2008-2017 Audi S5 or 2009-2016 S4 includes everything you need to significantly upgrade your front braking system. You get a pair of Brembo's 6-piston GT calipers, two 380x32mm two-piece brake rotors with a Type 3 slotting pattern, and all the necessary hardware for installation. This kit is designed to replace your factory setup with a much more robust and capable braking solution, ideal for drivers who push their cars hard or want the best possible stopping power.

The 6-piston calipers are cast from aluminum for a strong yet lightweight housing, and they work with larger brake pads to increase the pad surface area contacting the rotor. This larger contact patch, combined with the caliper's design, helps distribute heat more effectively and provides more consistent clamping force. The two-piece rotors feature a cast iron friction ring that bolts to an aluminum hat. This design helps reduce weight and manage heat, as the aluminum hat can dissipate heat away from the hub assembly. The 380mm diameter and 32mm thickness of the rotors offer substantial thermal mass, which is crucial for resisting fade during repeated hard stops. The Type 3 slotting pattern on the rotors is a popular choice for performance applications; these slots help sweep away dust and gas that can build up between the pad and rotor surface, maintaining optimal friction and providing a consistent pedal feel.

Installing a big brake kit like this is a significant upgrade, and it's recommended to have a qualified mechanic perform the installation to ensure everything is set up correctly. This kit is a comprehensive solution for anyone looking to improve their vehicle's braking performance for track days, spirited driving, or simply for the confidence that comes with having superior stopping power. You'll notice a dramatic improvement in braking feel, fade resistance, and overall stopping distance.
