Zimmermann 150.3466.55 Disc Brake Rotor - Rear or Rear Right

Zimmermann Black Z Rotor Overview

The Zimmermann 150.3466.55 is a slotted disc brake rotor built for BMW applications that require a 320 mm rear rotor with a 20 mm thickness. It combines high-carbon machining, a coated surface, and ECE R90 approval for a direct replacement solution with controlled braking performance.

Key Features

• Slotted brake disc design helps clear brake dust and water from the braking surface.
• High-carbon construction supports stable braking characteristics under heat.
• Coated surface adds corrosion resistance and a cleaner appearance.
• 320 mm outer diameter with 20 mm thickness and 18.4 mm minimum thickness.
• ECE R90 approved for regulated aftermarket brake replacement.

Detailed Description

Zimmermann Black Z rotors are engineered with a grooved braking surface and anti-corrosion coating to combine everyday durability with consistent wet-weather braking behavior. 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.

What It Is Used For

• Replacing a worn rear brake rotor on compatible BMW applications.
• Restoring braking smoothness when rotor wear has reached service limits.
• Reducing brake dust and water buildup on the rotor face.
• Addressing rotor corrosion that affects braking surface condition.
• Correcting vibration or braking inconsistency caused by rotor wear.

Installation Notes and Tips

Verify 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.

Quality Assurance

Zimmermann states that this rotor is ECE R90 homologated, which means it meets the approval standard referenced in the product data for regulated brake replacement.
