Brembo 09-15 CTS-V Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Red

This is the Brembo Rear GT Big Brake Kit for the 2009-2015 Cadillac CTS-V. It's a substantial upgrade designed to handle the demands of a high-performance vehicle like the CTS-V, offering improved stopping power and heat management over the stock setup. The kit includes four-piston calipers, large two-piece rotors, and all the necessary hardware to get them installed.

The calipers are cast aluminum, which keeps weight down while maintaining strength. They feature a four-piston design, meaning more clamping force is applied to the rotor surface for better braking. The rotors themselves are a two-piece design, measuring 380x28mm. This two-piece construction allows the rotor and the hat to expand and contract independently with heat, reducing the risk of warping. The rotors are also slotted, which helps to sweep away dust and gas that can build up between the pad and rotor, ensuring consistent braking performance, especially during repeated hard stops. The Type-1 finish on the rotors is a specific surface treatment designed to help seat the brake pads quickly and efficiently.

When installing a kit of this caliber, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is designed to be a direct fit for the specified CTS-V models, but it's always a good idea to double-check clearances, especially if you have aftermarket wheels. The improved braking performance will be noticeable, giving you more confidence when you need to slow down quickly.
