Brembo 05-1ster S/Spyder (Excl PCCB) Rr GTR BBK 4Pis Billet 345x28 2pc Rotor Drilled-Nickel

The 4-piston billet aluminum calipers in this Brembo Rear GTR Big Brake Kit are machined from solid blocks of aluminum, offering a strong yet lightweight foundation for serious braking performance. This kit is specifically designed for the 05-1ster S/Spyder models, excluding those equipped with PCCB (Porsche Ceramic Composite Brakes), and aims to significantly improve your vehicle's stopping power and heat management.

Each caliper houses four pistons, which apply more even pressure across the brake pad surface compared to smaller or single-piston designs. This results in more consistent braking force and better pedal feel, especially under demanding conditions. The kit includes 345x28mm two-piece rotors. The rotors feature a drilled surface, which helps dissipate heat and expel gases and dust away from the pad surface, maintaining optimal friction. The nickel finish on the rotors adds a layer of corrosion resistance, helping them look good and perform well over time. The two-piece design allows the rotor friction surface to expand and contract independently of the hub, reducing the risk of rotor warping under extreme heat.

This is a comprehensive kit designed for a direct upgrade to your rear braking system. While it's a significant performance enhancement, it's important to ensure compatibility with your specific wheel size, as larger calipers and rotors require adequate clearance. Refer to the manufacturer's installation instructions for detailed fitment and mounting procedures.
