Brembo 04-21 WRX STI Front GTR BBK 6 Piston Billet 350x34 2pc Rotor Slotted TY3L - Nickel

When you open the box for this Brembo GTR Big Brake Kit, you'll find a complete front-end upgrade designed for serious performance. This kit includes a pair of Brembo's robust 6-piston billet aluminum calipers, finished in a striking nickel coating, along with two-piece 350x34mm slotted rotors. You'll also get all the necessary hardware to get these components installed, ensuring you have everything needed for a comprehensive brake system overhaul.

This isn't just about bigger parts; it's about a significant improvement in how your WRX STI stops. The 6-piston calipers offer more clamping force and better heat dissipation than stock, working in tandem with the larger 350mm rotors. The two-piece rotor design helps manage heat and reduce unsprung weight, while the slotted surface helps clear out dust and gas, maintaining consistent braking performance even under demanding conditions. Brembo's billet aluminum construction for the calipers means they are both strong and lightweight, crucial for a high-performance braking system that needs to withstand extreme temperatures and forces.

Installing a big brake kit like this is a substantial upgrade, and it's often done when rebuilding the braking system or when seeking the ultimate in stopping power for track days or spirited driving. While this kit provides the core components, it's always a good idea to consult the manufacturer's installation guide for specific torque values and any other recommended procedures to ensure optimal performance and safety.
