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

If you're looking to significantly upgrade the braking performance on your 1997-2004 Porsche Boxster S, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to give you more stopping power and better heat management, which is crucial for spirited driving or track use. It replaces your factory rear brake components with larger, more robust parts that can handle more abuse without fading.

At the heart of this kit are the 4-piston aluminum calipers, which offer a stronger clamping force than stock. These calipers work with a pair of 345x28mm two-piece rotors. The two-piece design helps reduce unsprung weight and allows the rotor to expand and contract more freely with heat, which can prevent warping. The rotors are slotted with Brembo's Type-1 pattern, which helps to keep the pads clean and clear out gases and heat, ensuring consistent braking performance even under heavy load. The calipers come in a distinctive yellow finish, adding a visual upgrade to your vehicle.

This kit is a comprehensive upgrade, meaning it includes the calipers, rotors, and likely the necessary mounting hardware and brake lines to make the installation as straightforward as possible, though you should always refer to the manufacturer's instructions for specific details. Upgrading to a big brake kit like this can make a notable difference in how your car feels when you brake, especially during demanding driving conditions.
