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

This Brembo Rear GT Big Brake Kit is designed for the 2005-later S and Spyder models, specifically excluding those with PCCB (Porsche Ceramic Composite Brakes). What you get in this kit are 4-piston calipers, a pair of 345x28mm two-piece rotors that are drilled, and all the necessary hardware to get them installed. This is a significant upgrade over the stock braking system, aimed at drivers who demand more from their car's stopping performance.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while still being strong enough to handle the heat generated during hard braking. They utilize a 4-piston design, meaning more pad surface area contacts the rotor, leading to better force distribution and more consistent stopping power. The rotors are a two-piece design, with a 345mm diameter and 28mm thickness. The two-piece construction allows the rotor and the hat (the center part that mounts to the hub) to expand and contract independently with heat, which helps prevent warping. These rotors are also drilled, a feature that helps dissipate heat and gasses, keeping the pads cleaner and improving performance under heavy use.

Installing a big brake kit like this is a substantial modification. It's a project that requires careful attention to detail to ensure proper function and safety. While this kit is designed to fit the specified models, it's always a good idea to consult the manufacturer's installation guide for specific torque values and any other requirements. This kit is a serious investment in your vehicle's performance, offering a noticeable improvement in braking feel and fade resistance for spirited driving or track use.
