Brembo 07-13 X5 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Black

This Brembo GT Big Brake Kit for the rear of your 2007-2013 BMW X5 includes everything you need to significantly upgrade your braking system. You'll get a pair of Brembo's 4-piston GT calipers, two 380x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes with a much more robust setup, giving you improved stopping power and better heat management.

The calipers in this kit are cast aluminum, which keeps them strong yet relatively lightweight. They house four pistons, which means more even pressure is applied to the brake pads, leading to more consistent braking force and a better pedal feel. The two-piece rotors are a notable upgrade; the cast iron braking surface is separate from the aluminum hat. This design helps reduce unsprung weight and allows for better thermal management, as the hat can dissipate heat more effectively than a solid one-piece rotor. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, which is especially beneficial during repeated hard stops.

Upgrading your rear brakes with a kit like this is a significant step for any X5 owner looking for improved performance. It's important to ensure you have adequate cooling for your front brakes as well, to maintain a balanced braking system. Refer to the manufacturer's installation instructions for specific details on mounting and brake fluid requirements.
