Brembo 11-16 528i Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Silver

This is the Brembo GT Big Brake Kit for the rear of your 2011-2016 BMW 528i. It's designed to give your car a significant upgrade in stopping power and heat management, which is crucial if you're pushing your car hard or just want the best possible braking performance. This kit replaces your factory rear brake components with larger, more capable parts.

At the heart of this kit are the Brembo 4-piston calipers, which offer more clamping force than stock. They work with 345x28mm two-piece rotors that are drilled for better heat dissipation. The two-piece design allows the rotor hat to expand and contract independently of the friction surface, which helps prevent warping under heavy use. The drilled surface helps vent gases and heat away from the pad, keeping your brakes cooler and more consistent, especially during repeated hard stops. The calipers are cast aluminum for a good balance of strength and weight, and they come in a silver finish to look sharp behind your wheels.

When installing a kit like this, it's important to ensure all components are properly seated and torqued according to Brembo's instructions. This kit is a substantial upgrade, and it's designed to work as a complete system to provide reliable, high-performance braking. You'll notice improved pedal feel and a greater confidence in your car's ability to slow down quickly and safely, even when the brakes are hot.
