The 150.3466.55 uses a 6\/5 hole arrangement, 120 mm bolt circle, and 75 mm hub bore, making it a fitment-specific rotor for select BMW rear brake applications. This part cross-references Bosch 18042 and Brembo 09.B313.11 for the same application. For BMW 528i xDrive, 528xi, 535xi, 525xi, and 530xi applications, the rotor is matched to the listed rear fitments and dimensions. The Zimmermann 150.3466.55 is part of the Black Z line, which focuses on slotted rotors with coated surfaces for drivers who want a functional brake upgrade with a more refined finish.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn rear brake rotor on compatible BMW applications.\u003c\/li\u003e\n\u003cli\u003eRestoring braking smoothness when rotor wear has reached service limits.\u003c\/li\u003e\n\u003cli\u003eReducing brake dust and water buildup on the rotor face.\u003c\/li\u003e\n\u003cli\u003eAddressing rotor corrosion that affects braking surface condition.\u003c\/li\u003e\n\u003cli\u003eCorrecting vibration or braking inconsistency caused by rotor wear.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify rotor diameter, thickness, hub bore, and bolt pattern before installation. This rotor fits 2009-2010 BMW 528i xDrive, rear; 2008 BMW 528xi, rear; 2008 BMW 535xi, rear; 2006-2007 BMW 525xi, rear right; 2006-2007 BMW 525xi, rear; and 2006-2007 BMW 530xi, rear. Confirm the vehicle’s rear brake configuration and compare the existing rotor dimensions to the listed specifications before service. The part number 150.3466.55 should be matched to the application exactly, and the paired article number 150.3466.54 should be checked when servicing the opposite side or related axle position.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eZimmermann states that this rotor is ECE R90 homologated, which means it meets the approval standard referenced in the product data for regulated brake replacement.\u003c\/p\u003e","brand":"Zimmermann","offers":[{"title":"Default Title","offer_id":53534298931381,"sku":"BKND-150.3466.55","price":165.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/ZI_150346655_Fro.jpg?v=1792132557","url":"https:\/\/www.partcatalog.com\/products\/zimmermann-150-3466-55-disc-brake-rotor-rear-or-rear-right","provider":"PartCatalog","version":"1.0","type":"link"}
