The rotors are made to OEM-style specifications using G3000\/G11H18 cast iron, then machined to tight tolerances and finished to promote even pad contact. The coating is designed to provide a durable silver-gray appearance while helping protect against corrosion. The pads are formulated for stable friction and improved NVH control through premium shims. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon brake issues this kit addresses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake noise from worn hardware or pad movement\u003c\/li\u003e\n\u003cli\u003eRust buildup on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eUneven pad bed-in after rotor replacement\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency from fatigued friction components\u003c\/li\u003e\n\u003cli\u003eCorrosion-related service delays during brake repair\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes and tips\u003c\/h2\u003e\u003cp\u003eCompatible with 2020-2023 BMW 840i, front and rear; 2020-2023 BMW 840i Gran Coupe, front and rear; 2020-2023 BMW 840i xDrive, front and rear; 2020-2023 BMW 840i xDrive Gran Coupe, front and rear; 2019-2022 BMW M850i xDrive, front and rear; 2020-2022 BMW M850i xDrive Gran Coupe, front and rear; and 2021-2022 BMW X5, front and rear.
