This comprehensive front and rear kit features oversized four-piston calipers with integrated pads, wear sensors, and necessary hardware for the front wheels. The front also includes dimpled, slotted, and vented oversized rotors measuring 370x30, along with rotor shield protection plates for enhanced durability and performance. For the rear, the kit provides oversized two-piston calipers with pads, wear sensors, and hardware, as well as rotor shield protection plates. It is important to note that this kit does not include rear rotors. Installation requires specific, larger rear rotors such as the F30 335i: ES#2568632, F30 328i: ES#2568783, F31 328d: ES#2537262, or F30 330i: ES#2568632. This big brake kit is engineered for a range of BMW F22, F23, F30, F31, F32, F33, F34, and F36 models, typically from 2014-2020, with specific engine fitments including B46, B58, N20, N47, N55, and B48. Always verify fitment with the vehicle selector to ensure compatibility with your specific vehicle's year, model, submodel, and engine. The kit offers a significant upgrade in both performance and aesthetics, providing a sporty look behind the wheels.
