Brembo 12-14 328i MSport Brakes Excl xDrive Rr GTS BBK 4Pis Cast 345x28 2pc Rtr Slot Type1-Black HA

This Brembo rear big brake kit is specifically designed for the 2012-2014 BMW 328i M Sport models, excluding the xDrive variants. It's a substantial upgrade over the factory setup, featuring a four-piston caliper and a large 345x28mm two-piece rotor designed to handle the demands of spirited driving and track use. If you're looking to significantly improve your car's stopping power and heat management, this kit is a solid choice.

The kit includes cast aluminum calipers with a four-piston design, which offers more clamping force and better pad distribution compared to smaller, single-piston calipers. The rotors are a two-piece design, meaning the hat and the friction ring are separate. This construction helps reduce weight and allows for better thermal management, as the hat can expand and contract more freely without inducing stress into the rotor ring. The friction ring itself is 345mm in diameter and 28mm thick, providing a larger surface area for braking and increased thermal capacity. These rotors feature a Type 1 slotting pattern, which helps to keep the pad surface clean and clear out gases and dust generated during braking, ensuring more consistent performance, especially under heavy use. The calipers are finished in black with a Type 1 slotting pattern on the rotors.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. While this kit is designed as a direct bolt-on for the specified models, it's always recommended to consult the included installation guide for any specific torque values or procedures. Upgrading your rear brakes to this Brembo kit will provide a noticeable improvement in braking feel and fade resistance, complementing any performance modifications you may have made to your vehicle.
