Brembo 08 - 14 WRX STi (GR/ GV) PISTA Rear Race BBK 2pc 345x28x54a 2pc Rotor T5

The 345x28mm rotor dimensions on this Brembo PISTA rear brake kit are a key indicator of its performance focus. This kit is specifically built for the 2008-2014 Subaru WRX STi models with the GR/GV chassis, offering a significant upgrade over the factory braking system. It's designed for drivers who push their vehicles hard and need consistent, strong stopping power when it matters most.

This isn't just a set of rotors and calipers; it's a complete Big Brake Kit (BBK) engineered by Brembo, a name synonymous with high-performance braking. The two-piece rotor design is notable because it helps manage heat more effectively. The floating hat allows the rotor ring to expand and contract independently, reducing the risk of warping and ensuring a more stable contact surface for the brake pads. This setup is crucial for track use or aggressive driving where brake temperatures can soar.

When you're installing a kit like this, you're looking at a substantial improvement in braking performance. The larger rotor surface area and the robust caliper design work together to dissipate heat and provide more leverage for stopping. While this kit is designed for performance, it's important to remember that it's intended for race applications and may require specific brake pads and fluid to achieve its full potential. Always refer to the manufacturer's installation guide for the most accurate fitment and setup details.
