Brembo 09-16 Panamera/S/4S/Turbo Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-White

This Brembo GT Big Brake Kit for the rear of your 2009-2016 Porsche Panamera, Panamera S, Panamera 4S, or Panamera Turbo gives you a substantial upgrade in stopping power and heat management. What you get in this kit are the essential components to transform your braking system: a pair of Brembo 4-piston GT calipers, two 380x28mm two-piece rotors with a slotted design, and all the necessary hardware to get them installed. This isn't just about stopping faster; it's about maintaining consistent performance even under heavy use, like during spirited driving or track days.

The calipers themselves are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Brembo's GT calipers are known for their stiffness, meaning more of your pedal effort goes directly into clamping the rotor, not flexing the caliper. The two-piece rotors are a smart design choice; the cast iron friction ring is attached to an aluminum hat. This separation allows for better thermal management, as the hat can dissipate heat more effectively than a solid one-piece rotor, and it also helps reduce the risk of rotor warping under extreme temperatures. The Type 1 slotting pattern on the rotors is designed to help sweep away dust and gas that can build up between the pad and rotor surface, ensuring a cleaner contact patch and more reliable braking performance, especially when things get hot.

Upgrading your rear brakes with a kit like this is a significant step towards a more capable and confidence-inspiring driving experience. Because this is a comprehensive kit, it's designed to work together as a system. Always refer to the manufacturer's installation instructions for specific details on mounting the calipers and rotors, and ensure you have the correct brake fluid for bleeding the system afterward.
