Brembo 08-17 A5 Front GTS BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type1-Black HA

This Brembo Gran Turismo Sport (GTS) Big Brake Kit (BBK) for your 2008-2017 Audi A5 includes everything you need to significantly upgrade your front braking system. You'll get a pair of massive 380x34mm two-piece rotors, a set of six-piston cast aluminum calipers finished in black with the HA (High-Performance Aluminum) designation, and all the necessary hardware to get them installed. This kit is designed to replace your factory front brakes with a much more robust setup, offering improved stopping power and heat management for spirited driving or track use.

The two-piece rotor design is a notable feature here. The rotor itself is made from a high-carbon cast iron, and it's attached to a lightweight aluminum hat. This construction helps reduce unsprung weight and allows for better thermal expansion, which can prevent rotor warping under heavy use. The rotors are also slotted with Brembo's Type 1 pattern, which helps to sweep away dust and gas buildup that can form between the pad and rotor surface. This means more consistent braking performance, especially when you're pushing your car hard. The six-piston calipers are cast from aluminum, making them strong yet relatively light, and they offer a larger piston area than stock. This increased piston area means more clamping force is applied to the rotors for improved stopping power.

Installing a big brake kit like this is a significant upgrade, and it's often done when a vehicle is used for performance driving or track days. The larger rotors and calipers dissipate heat more effectively than the factory components, reducing the risk of brake fade during prolonged use. While this kit is designed as a direct replacement for the factory front brake components, it's always a good idea to consult the manufacturer's installation guide for specific torque specifications and any other required procedures. You'll likely notice a substantial difference in pedal feel and braking performance after installation.
