Brembo 23+ Z (RZ34) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Black

The 380x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat and provide a solid foundation for braking performance. This rear kit is designed for vehicles that demand more from their braking system, especially when pushing the limits. The four-piston calipers are a key component, offering increased clamping force over stock setups, which translates directly into better stopping power and feel.

Brembo's GT BBK is a well-known upgrade for a reason. The two-piece rotor design, with its cast iron friction surface and aluminum hat, helps manage heat more effectively. This design reduces the risk of rotor warping under heavy use, a common issue with factory components during spirited driving or track events. The drilled rotor faces help dissipate heat and gases, ensuring consistent performance even when the brakes are working hard. The black finish on the calipers and rotors adds a clean, performance-oriented look to your vehicle's wheels.

This kit includes everything you need to upgrade your rear braking system. You'll find the four-piston calipers, the two-piece 380x28mm drilled rotors, and all the necessary hardware for installation. While this is a comprehensive kit, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures to ensure optimal performance and safety. This upgrade is a substantial change from your factory brakes, offering improved fade resistance and a more direct pedal feel.
