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

If you're looking to significantly upgrade the braking performance of your 1997-2004 Porsche Boxster, a Big Brake Kit (BBK) like this one from Brembo is a serious consideration. This kit is specifically designed for the rear of your 986 chassis, aiming to provide improved stopping power and heat management for spirited driving or track use. It replaces your factory rear brake components with larger, more capable parts that can handle the demands of harder braking.

At the heart of this kit are the 4-piston aluminum calipers, which offer greater clamping force than stock. These calipers work with substantial 345x28mm two-piece rotors. The two-piece design allows the rotor and the hat to expand and contract independently, which can help reduce the risk of rotor warping under extreme heat. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to sweep away dust and gas buildup, maintaining consistent pad contact and improving wet weather performance. The cast iron rotor construction is well-suited for the heat generated during heavy braking.

This Brembo kit includes everything needed to convert your rear brakes to this higher-performance setup. You'll find the calipers, the two-piece rotors, and likely all the necessary mounting hardware and brake lines to complete the installation. It's a comprehensive package aimed at delivering a noticeable improvement in braking feel and fade resistance. Remember to consult the included installation instructions for specific details on fitting this kit to your Boxster.
