Brembo 11-17 X3/15-18 X4 Front GT BBK 6 Piston Cast 380x32 2pc Rotor Slotted Type1-Red

This Brembo GT Big Brake Kit for the front of your 2011-2017 BMW X3 or 2015-2018 BMW X4 includes everything you need to significantly upgrade your braking system. You get a pair of red 6-piston cast iron calipers, two 380x32mm two-piece slotted rotors, high-performance brake pads, and all the necessary mounting hardware and stainless steel braided brake lines. This kit is designed to replace your factory brake components with a more robust and capable setup, offering improved stopping power and heat management for spirited driving and demanding conditions.

The heart of this kit lies in its 6-piston calipers, which distribute braking force over a larger area and provide a more consistent pedal feel. The rotors are a substantial 380mm in diameter and 32mm thick, featuring a two-piece construction with a cast iron friction ring and an aluminum hat. This design helps reduce weight and allows for better thermal management by separating the heat-generating friction surface from the hub. The Type 1 slots on the rotor surface are engineered to help clear away brake dust and gases, which can improve pad contact and maintain consistent braking performance, especially under heavy use. The included brake pads are specifically chosen to complement the caliper and rotor combination for optimal performance.

Installing a big brake kit like this is a significant upgrade that can transform your vehicle's driving dynamics. The stainless steel braided brake lines included in the kit resist expansion under pressure, leading to a firmer and more responsive pedal feel compared to standard rubber hoses. While this kit is designed as a direct replacement for the factory brake system, it's always recommended to consult the manufacturer's installation guide for specific procedures and torque specifications. This Brembo GT BBK is a well-built system for those looking for a serious improvement in braking performance and durability.
