Brembo 12-14 328i MSport Brakes Excl xDrive Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot TY3L - Black

If you're looking to significantly improve your BMW 328i MSport's braking performance, especially for track days or spirited driving, this Brembo GT Big Brake Kit for the rear is a substantial upgrade. This kit replaces your factory rear braking components with a much larger and more capable setup, designed to handle the heat and demands of performance driving. It's built to work with your 328i's MSport package, excluding xDrive models, and features a striking black caliper finish.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over stock. These calipers grip large 345x28mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which can help reduce stress and prevent warping. The rotors themselves are slotted, a feature that helps to vent dust, gas, and heat away from the pad surface. This slotting pattern is specifically designed by Brembo to maintain consistent braking performance even under heavy use, preventing glazing and ensuring a solid pedal feel. The cast aluminum construction of the calipers is chosen for its strength and ability to dissipate heat effectively, crucial for maintaining braking power lap after lap.

This Brembo GT Big Brake Kit is a comprehensive rear-end upgrade. It includes everything needed to install the larger calipers and rotors, transforming your 328i's rear braking system. For optimal performance and safety, it's recommended to consult the manufacturer's installation guide and consider pairing this rear kit with a compatible front big brake kit for balanced braking power across the entire vehicle.
