Brembo 18+ X3/19+ X4 Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type1-Silver

This Brembo GT Big Brake Kit for the front of your 2018+ BMW X3 or 2019+ BMW X4 includes everything you need for a significant upgrade in braking performance. You get a pair of massive 380x34mm two-piece rotors with a slotted design, six-piston calipers cast from durable aluminum, and all the necessary hardware to get them installed. This kit is designed to replace your factory braking components and offer a more robust and responsive feel, especially under demanding conditions.

The heart of this kit is the six-piston caliper, which uses larger pistons to distribute braking force more evenly across the 380mm rotor surface. This increased surface area and piston count mean more clamping power and better heat dissipation. The two-piece rotor construction, featuring a cast-iron friction ring bolted to an aluminum hat, helps reduce unsprung weight and allows for better thermal management by isolating heat between the two components. The Type 1 slots on the rotor faces are there to help sweep away dust and gas that can build up between the pad and rotor, ensuring consistent grip and performance, especially during repeated hard stops.

Installing a big brake kit like this is a substantial modification, and it's recommended to have a qualified mechanic perform the work. This kit is a popular choice for drivers who push their vehicles hard, whether on track days or spirited canyon drives, and want a braking system that can keep up. You'll notice improved pedal feel and a greater confidence in your stopping power, even after repeated heavy braking.
