Product Details
This is the Brembo Rear GT Big Brake Kit for the 2023 and newer Nissan Z (RZ34) model. It's a comprehensive upgrade designed to significantly improve your braking performance, especially if you're pushing the car hard on the track or demanding spirited street driving. This kit replaces your factory rear brake components with larger, more capable parts, including four-piston calipers and a two-piece rotor assembly.
The kit features a cast aluminum four-piston caliper, which offers a solid foundation for consistent stopping power. Paired with the 380x28mm two-piece rotors, which are drilled for heat dissipation, you get a setup that can handle more abuse before experiencing fade. The two-piece design also helps manage heat and can make rotor replacement simpler down the line. Brembo finishes these calipers in a striking fluorescent yellow, adding a visual upgrade to match the performance gains. This is a well-built system from a brand known for its braking technology.
When installing this kit, you'll be replacing your stock calipers and rotors. The kit includes the calipers, rotors, and likely the necessary mounting hardware and brake lines for a complete conversion. It's important to ensure you have the correct brake fluid for a full system bleed after installation. This kit is a substantial upgrade for the serious enthusiast looking for the best in braking performance for their Z car.
