Brembo 23+ Z (RZ34) Rear GTR BBK 4 Piston Billet380x28 2pc Rotor Drilled- Nickel Plated

This is the Brembo 23+ Z (RZ34) Rear GTR Big Brake Kit, designed for serious performance braking. It features a robust 4-piston billet aluminum caliper paired with a 380x28mm two-piece drilled rotor. The nickel plating on the caliper housing offers a layer of protection and a distinct look, while the drilled rotor design helps dissipate heat and reduce weight compared to solid rotors. This kit is built for vehicles where stopping power and heat management are critical, offering a significant upgrade over stock braking systems.

The caliper itself is a 4-piston design, meaning it uses four individual pistons to apply pressure to the brake pads. This allows for more even pad wear and a more consistent pedal feel, especially under heavy braking conditions. The two-piece rotor construction separates the braking surface from the hat, which helps to reduce thermal stress and prevent warping. The hat is typically made from a lighter material, further reducing unsprung weight. The drilled pattern on the rotor surface is not just for looks; it helps to vent gases and heat away from the pad surface, which can improve braking performance in demanding situations and reduce the risk of brake fade.

This kit includes the necessary components for a comprehensive rear brake upgrade. When installing a big brake kit like this, it's important to ensure your master cylinder and brake booster are up to the task of providing adequate hydraulic pressure. While this kit is designed for direct fitment on specific applications, always refer to the manufacturer's installation instructions for detailed guidance and any additional hardware or modifications that may be required for your particular vehicle. Proper installation is key to realizing the full performance potential and safety benefits of this high-performance braking system.
