Brembo 06-12 325i/328i (Excl. xDrive) Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of your 2006-2012 BMW 325i or 328i (excluding xDrive models) includes everything you need to significantly upgrade your braking system. You get a pair of Brembo 4-piston cast aluminum calipers, two 2-piece 345x28mm rotors with a drilled finish, caliper mounting brackets, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake components with a more robust and capable setup, offering improved stopping power and heat management.

The calipers in this kit are forged from cast aluminum, which is strong yet lightweight, helping to reduce unsprung weight. They feature a 4-piston design, meaning more pad surface area contacts the rotor, which translates to better clamping force and more consistent braking. The 2-piece rotors are a substantial 345mm in diameter and 28mm thick, providing ample thermal mass to absorb and dissipate heat generated during hard braking. The drilled finish on the rotors helps to vent gases and moisture, further aiding in heat dissipation and maintaining braking performance, especially during repeated stops.

Installing a big brake kit like this is a significant upgrade that can make a noticeable difference in how your car feels when slowing down, particularly under demanding conditions. It's a solid option if you're looking to enhance the performance and responsiveness of your BMW's rear braking system. Be sure to consult the manufacturer's installation guide for specific details on mounting the calipers and rotors, as well as any recommended brake fluid types for optimal performance.
