Brembo 06 330i Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Black HA

This is the Brembo 4-piston rear Big Brake Kit (BBK) specifically for the BMW 330i (E46 generation). It's a comprehensive upgrade designed to significantly improve your rear braking performance. If you're looking to get the most out of your 330i on the street or track, this kit offers a substantial step up from the factory setup.

At the heart of this kit are the 4-piston cast aluminum calipers, finished in a sleek black HA coating for durability and looks. These calipers grip the substantial 345x28mm two-piece rotors, which are slotted with Brembo's Type1 pattern. The two-piece rotor design helps manage heat more effectively by allowing the hat and the friction surface to expand independently, reducing the risk of warping. The slots on the rotor surface help to sweep away dust and gas buildup, ensuring consistent contact between the pad and rotor, especially during hard braking. This combination is built to handle the demands of spirited driving and track use, offering improved stopping power and fade resistance.

This kit includes everything you need to get your BMW 330i's rear brakes upgraded. You'll find the calipers, the two-piece slotted rotors, and all the necessary hardware for installation. It's a well-built system from Brembo, a name known for its high-performance braking components. When installing a kit like this, it's always a good idea to consult the manufacturer's instructions to ensure proper fitment and function, especially regarding brake fluid and bedding-in procedures.
