Brembo 05-1ster S/Spyder (Excl PCCB) Rr GT BBK 4Pis Cast 345x28 2pc Rotor Drilled-Silver

If you're looking to significantly upgrade your Porsche Boxster or Cayman's 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 more robust setup, offering improved stopping power and heat management for spirited driving or track use. It features a 4-piston caliper and a 345x28mm two-piece rotor, engineered to handle the demands of higher performance vehicles.

The heart of this kit is Brembo's renowned GT caliper, known for its solid construction and consistent performance. It's paired with a two-piece rotor assembly, where the cast iron friction ring is attached to an aluminum hat. This design helps reduce weight and allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid one-piece rotor. The rotors are drilled, which helps to vent gases and moisture away from the pad surface, contributing to more consistent braking, especially under heavy use. The calipers are finished in a silver powder coat for a clean look behind your wheels.

This kit includes everything needed to upgrade your rear brakes, such as the calipers, rotors, and necessary hardware for installation. It's important to note that this kit excludes vehicles equipped with Porsche's Ceramic Composite Brakes (PCCB). For optimal performance and longevity, it's always recommended to follow the manufacturer's installation instructions carefully and consider pairing these rear upgrades with a suitable front brake kit for balanced braking performance.
