Brembo 06-12 325i/328i (Excl. xDrive) Rr GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black

This Brembo GT Big Brake Kit for the rear of your 2006-2012 BMW 325i or 328i (excluding xDrive models) includes everything you need to significantly upgrade your braking performance. You get a pair of 4-piston calipers, two 345x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brake setup with a much more robust system, offering improved stopping power and heat management.

The calipers are cast from high-strength aluminum and feature a 4-piston design, which allows for more even pad pressure and better heat dissipation compared to smaller factory calipers. The rotors are a two-piece design, meaning the hat and the friction ring are separate. This construction helps reduce weight and allows the rotor to expand and contract more freely under heat, minimizing the risk of warping. The slots machined into the rotor surface help to vent gases and dust away from the pad surface, maintaining consistent braking performance even under heavy use. The black finish on the calipers adds a clean, performance-oriented look to your vehicle.

Upgrading to a big brake kit like this is a substantial modification that can make a notable difference in how your car feels, especially during spirited driving or when carrying heavier loads. It's a solid option for owners looking to enhance their vehicle's braking capabilities beyond what the stock system can offer. Be sure to consult the manufacturer's installation instructions for specific details on mounting and brake fluid requirements.
