Brembo 12-14 328i MSport Brakes Excl xDrive Rr GTR BBK 4Pis Billet 345x28 2pc Rtr Slot Type1-Nickel

If you're looking to significantly improve your BMW 328i M Sport's braking performance, especially for track days or spirited driving, this Brembo GTR Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the heat and stress that come with demanding use, offering a more consistent and powerful pedal feel when you need it most. It's a comprehensive package aimed at giving your 328i the stopping power to match its performance capabilities.

At the heart of this kit are the 4-piston GTR calipers, known for their robust construction and excellent thermal management. They work in tandem with the 345x28mm two-piece slotted rotors. The two-piece design helps manage heat expansion and reduces unsprung weight, while the slots on the rotor surface help to vent gases and debris, keeping the pad surface clean for consistent grip. The Type 1 slot pattern is chosen for its balance of performance and durability. These components are built to work together, providing a substantial improvement over the factory braking system, especially under repeated hard braking.

This kit includes everything needed to upgrade your rear brakes, featuring the calipers, rotors, and necessary hardware for installation. It's a well-built system from Brembo, a name trusted in high-performance braking. While this kit is designed for a direct fit on the specified 328i M Sport models (excluding xDrive), it's always a good idea to consult the manufacturer's installation guide for any specific tool requirements or procedures. This is a substantial investment in your vehicle's safety and performance, offering a noticeable difference in stopping distance and fade resistance.
