Brembo 06-12 325xi/328xi Front GTS BBK 4 Piston Cast 365x29 2pc Rotor Drilled-Black HA

If you're looking to significantly improve your BMW 325xi or 328xi's stopping power, especially for track days or spirited driving, this Brembo GTS Big Brake Kit is a serious upgrade for the front axle. This kit replaces your factory braking components with a much larger and more robust system designed to handle higher temperatures and provide more consistent braking performance when you need it most. It’s a comprehensive package that addresses the demands of performance driving.

At the heart of this kit are the 4-piston aluminum calipers, which offer increased clamping force over stock. These calipers work with substantial 365x29mm two-piece rotors. The two-piece design helps manage heat by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors themselves are drilled, which helps dissipate heat and gases, contributing to a more stable pedal feel under heavy braking. This entire assembly is finished in black for a clean, performance-oriented look behind your wheels.

Installing a big brake kit like this is a significant modification, and it's designed to be a direct fit for the specified BMW models, meaning no custom fabrication is typically required. You'll notice a substantial difference in braking performance, with shorter stopping distances and improved fade resistance during repeated hard stops. This kit is a well-built solution for drivers who push their vehicles and demand more from their braking system.
