Brembo 97-04 986 Boxster S Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Silver

If you're looking to significantly improve the stopping power and heat management on your 1997-2004 Porsche Boxster S, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory braking system. It features a robust 4-piston caliper and a large 345x28mm two-piece rotor designed to dissipate heat effectively.

The heart of this kit is Brembo's renowned engineering. The calipers are cast aluminum for a good balance of strength and light weight, housing four pistons that apply even pressure across the pad surface for consistent braking. These calipers are paired with a two-piece rotor assembly, where the rotor disc is separate from the hat. This design allows for better thermal management, as the hat can expand and contract independently of the rotor, reducing the risk of warping. The rotors themselves are slotted, which helps to sweep away dust and gas that can build up between the pad and rotor surface, maintaining optimal friction and preventing fade under heavy use. The Type-1 finish on the rotors and the silver caliper finish offer a clean, performance-oriented look.

This kit is a comprehensive solution for your Boxster S's rear braking system. It includes everything needed to install the larger calipers and rotors, transforming your car's ability to slow down reliably, especially during repeated hard braking events. When installing a big brake kit like this, it's always a good idea to check your brake fluid and consider a high-performance fluid to match the capabilities of the new hardware.
