Brembo 11-18 Cayenne/S/GTS Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type3- Yellow

The 380x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its ability to handle heat and provide consistent stopping power. This kit is specifically for the rear of your 2011-2018 Porsche Cayenne, including S and GTS models, and features a 4-piston caliper design. The calipers themselves are finished in a bright yellow, adding a visual upgrade to your vehicle's stance.

This is a substantial upgrade over the factory braking system. The larger rotors offer more surface area for heat dissipation, which is crucial during spirited driving or when carrying heavy loads. The 4-piston calipers clamp down with more force and even pressure across the pad surface, leading to improved braking feel and reduced stopping distances. The rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction even under demanding conditions. Because these are two-piece rotors, the cast iron braking surface is attached to a lighter aluminum hat, reducing unsprung weight and helping to manage thermal expansion.

When installing a kit of this caliber, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is designed as a direct replacement for the rear axle, but it's always a good idea to check compatibility with your specific wheel size to confirm clearance. You'll notice a significant difference in braking performance and confidence after installation.
