Brembo 08-14 WRX STI Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - 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 four-piston cast aluminum calipers, two-piece 345x28mm slotted rotors, and all the necessary hardware to get them installed. This kit is designed to give your STI a serious boost in stopping power, especially during repeated hard braking situations.

The calipers are Brembo's well-known GT series, featuring a robust four-piston design that offers increased clamping force over stock. They are cast from aluminum for a good balance of strength and weight. The rotors are a two-piece design, which helps manage heat more effectively than a single-piece rotor. They measure 345mm in diameter and are 28mm thick, with a slotted surface. These slots help to vent gases and heat away from the pad surface, which means more consistent braking performance when you really push your car.

Installing a big brake kit like this is a substantial upgrade, and it's recommended to consult the manufacturer's installation guide for specific procedures. This kit is a popular choice for WRX STI owners looking for track-ready braking performance that can also handle spirited street driving. You'll notice improved pedal feel and significantly more confidence when braking hard.
