Product Details
If you're looking to significantly improve the braking performance of your 2012-2014 BMW 328i (excluding xDrive and M Sport models), this Brembo GT Big Brake Rear Kit is a substantial upgrade. This kit is designed to provide more stopping power and better heat management for the rear wheels, complementing any front brake modifications or simply enhancing the factory setup.
At the heart of this kit are the 4-piston calipers, which offer increased clamping force over stock calipers. These calipers are paired with large 345x28mm two-piece rotors. The two-piece design helps reduce unsprung weight and allows for better thermal management, as the rotor hat can expand and contract independently of the friction surface. The rotors feature Brembo's Type 3 slotting pattern, which helps to keep the pads clean and clear out gases and heat during aggressive braking, ensuring consistent performance when you need it most. The calipers themselves are cast from high-strength aluminum for a good balance of durability and weight savings, and they come finished in a sleek black to enhance the look of your wheels.
This kit includes everything needed to upgrade your rear braking system, featuring the calipers, two-piece rotors, and necessary mounting hardware. It's a comprehensive solution for drivers seeking a noticeable improvement in braking feel and fade resistance, especially during spirited driving or track use. Proper installation will ensure you get the most out of this well-built braking system.
