Brembo 23+ Z (RZ34) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Silver

If you're looking to significantly upgrade your vehicle's rear braking performance, this Brembo GT Big Brake Kit is a serious consideration. This kit is designed to replace your factory rear brake components with a much larger and more capable setup, featuring 4-piston calipers and substantial 380x28mm two-piece rotors. The goal here is to handle more heat and provide more consistent stopping power, especially during repeated hard braking situations like track days or spirited driving.

At the heart of this kit are the Brembo GT series 4-piston calipers, known for their solid construction and ability to apply even pressure across the larger brake pads. These calipers are paired with 380x28mm two-piece rotors. The two-piece design helps manage heat expansion and reduces unsprung weight compared to a solid one-piece rotor of similar size. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade. The silver finish on the calipers adds a clean, performance-oriented look behind your wheels.

This kit includes everything you need to perform the rear brake upgrade, such as the calipers, rotors, caliper mounting brackets, brake lines, and pads. Because this is a significant brake system upgrade, it's important to ensure it's compatible with your specific vehicle's wheel size and offset, as the larger calipers and rotors require adequate clearance. For installation, it's recommended to consult the manufacturer's instructions and consider professional installation due to the complexity of brake system modifications.
