Brembo 04-21 WRX STI Front GTS BBK 6 Piston Cast 350x34 2pc Rotor Slotted Type3-Black HA

This is the Brembo 6-piston GTS Big Brake Kit for the front of your 2004-2021 Subaru WRX STI. This kit is designed to significantly improve your braking performance, offering more stopping power and better heat management for spirited driving and track use. It replaces your factory front brake setup with a much larger and more robust system.

At the heart of this kit are the 6-piston cast aluminum calipers, finished in black with the HA designation, which indicates a specific internal design for optimal fluid flow. These calipers grip large 350x34mm two-piece rotors. The rotors are slotted, which helps to vent gases and debris away from the pad surface, maintaining consistent braking performance even under heavy load. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping and making replacement easier down the line. This kit is a substantial upgrade over stock, built with Brembo's reputation for high-performance braking components.

When installing a big brake kit like this, it's important to note that it's a comprehensive system. While it's designed as a direct fit for the specified WRX STI models, you'll want to ensure you have the necessary tools and potentially a helper for the installation. It's also a good idea to check your wheel clearance to make sure the larger calipers and rotors will fit inside your current wheel setup. This kit is a serious investment in your vehicle's performance and safety.
