Brembo 08-13 128i/08-13 135i Front GT BBK 6 Piston Cast 355x32 2pc Rotor Slotted Type1-Yellow

Brembo is well-known for making high-performance braking components, and this Front GT Big Brake Kit (BBK) is a prime example of their expertise. If you're looking to significantly upgrade the stopping power and feel of your 2008-2013 BMW 128i or 135i, this kit is designed to do just that. It replaces your factory front brakes with a much more robust system, giving you improved performance for spirited driving or track use.

This kit features a pair of Brembo's 6-piston GT calipers, which offer a larger piston area for more consistent clamping force and better heat dissipation compared to smaller calipers. They mount to 355x32mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which can help reduce the risk of rotor warping under heavy use. These rotors are slotted, meaning they have grooves machined into the surface. The slots help to sweep away dust and gas that can build up between the pad and rotor, maintaining a cleaner contact surface and improving braking consistency, especially during repeated hard stops.

Everything you need to install this front brake upgrade is included in the kit. This means you get the calipers, the two-piece slotted rotors, high-performance brake pads, and all the necessary mounting hardware and stainless steel brake lines. The calipers themselves are cast aluminum for a good balance of strength and weight, and they come in a bright yellow finish. When installing this kit, you'll want to ensure you have the proper tools and refer to the manufacturer's instructions for the correct procedures, as it's a significant upgrade from the stock braking system.
