Brembo 04-17 WRX STi/18-21 WRX STI Front GT BBK 6 Piston Cast 350x34 2pc Rotor Slotted Type3-Silver

If you're pushing your Subaru WRX STI hard on the track or autocross course, you know that stopping power is just as important as going fast. This Brembo GT Big Brake Kit is designed to give you the confidence to brake later and harder, lap after lap. It's a complete front brake upgrade that replaces your factory components with a much more robust system built for demanding use.

At the heart of this kit are the massive 6-piston calipers, which offer a larger piston area than stock. This means more clamping force on the rotors, translating to improved stopping performance. The calipers are paired with 2-piece, 350mm x 34mm slotted rotors. The two-piece design helps manage heat by allowing the rotor and hat to expand independently, and the slots help to vent gases and dust away from the pad surface, maintaining consistent braking performance even under extreme conditions. The Type 3 slotting pattern is a popular choice for its balance of performance and rotor longevity. The calipers come in a silver finish, giving your WRX STI a race-ready look.

This kit is a comprehensive upgrade, meaning it includes everything you need to get your WRX STI stopping like a champion. Brembo is well-known for their high-performance braking systems, and this GT Big Brake Kit is a testament to their expertise. While installation will require some mechanical know-how, it's designed to be a direct replacement for the factory setup, meaning no major modifications are needed. You'll want to ensure you have the correct brake fluid and potentially a brake bleeding kit on hand for the installation process.
