Brembo 08-14 WRX STI Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Silver

This Brembo GT Big Brake Kit for the rear of your 2008-2014 Subaru WRX STI includes everything you need to significantly upgrade your braking performance. You get a pair of Brembo 4-piston cast aluminum calipers, two 345x28mm 2-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the stock braking system.

The calipers are constructed from cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Inside, you'll find four pistons per caliper, working together to apply consistent and strong clamping force to the rotors. The rotors themselves are a 2-piece design, measuring 345mm in diameter and 28mm thick, which helps with heat dissipation and reduces the risk of warping under heavy use. The slots on the rotor surface are designed to help clear out dust and gas, ensuring that the brake pads maintain good contact and consistent performance, especially during repeated hard stops.

Installing a big brake kit like this is a significant upgrade, and it's often paired with front brake upgrades to create a balanced braking system. Make sure you have the appropriate brake fluid and consider a brake fluid flush and bleed after installation to get the most out of this Brembo kit. This is a well-built system designed for drivers who push their vehicles hard and demand reliable stopping power.
