Zimmermann 150.3466.54 Disc Brake Rotor - Rear or Rear Left

Overview

The Zimmermann Black Z disc brake rotor combines a slotted braking surface with high-carbon machining and a coated finish for controlled braking performance and corrosion resistance. It is built for BMW applications that require a 320 mm rear rotor, including BMW 528i xDrive, BMW 528xi, BMW 535xi, BMW 525xi, and BMW 530xi fitments.

Part number 150.3466.54 is an ECE R90 approved rotor with a grooved design that helps move brake dust and water away from the friction surface. The Black Z rotor line focuses on stable braking behavior and a more refined appearance without changing the original fitment dimensions.

Key Features

• Slotted brake disc design for consistent surface cleaning during braking.
• High-carbon machining for improved thermal stability under repeated stops.
• Coated surface helps resist corrosion and maintain appearance.
• ECE R90 approved for regulated replacement use.
• 320 mm outer diameter, 20 mm thickness, 75 mm hub bore, and 6/5 hole arrangement.

Detailed Description

Zimmermann developed the Black Z rotor line using experience from standard brake rotor production and motorsport-informed engineering. This rotor uses a grooved braking surface and coated finish to improve wet braking behavior by helping expel water and brake dust from the contact area. For BMW rear brake service, part number 150.3466.54 provides the specified dimensions and construction needed for applications such as BMW 528i xDrive, BMW 528xi, BMW 535xi, BMW 525xi, and BMW 530xi.

The Black Z range is intended for drivers who want a replacement rotor with a more technical surface design and corrosion-resistant coating while maintaining OE-style fitment. Part number 150.3466.54 also cross-references Bosch 18042 and Brembo 09.B313.11 for the same application.

What It Helps Address

• Brake fade caused by heat buildup during repeated stops.
• Reduced braking consistency in wet conditions.
• Surface corrosion on exposed brake rotor faces.
• Brake dust accumulation on the friction surface.
• Rotor replacement needs for worn rear brake discs.

Installation Notes

Verify rotor dimensions, hub bore, bolt pattern, and minimum thickness before installation. This rotor is a direct-fit replacement for listed BMW rear applications, including BMW 528i xDrive and BMW 530xi fitments. Confirm the vehicle’s brake specification matches the 320 x 20 mm rotor requirement and the listed rear position before service. Part number 150.3466.54 should be matched to the paired rotor reference when replacing brake components on the same axle.

Quality Assurance

This rotor is ECE R90 approved and marked accordingly. Zimmermann’s Black Z line is engineered as a regulated replacement brake rotor with coated corrosion protection and application-specific dimensions for the listed BMW models.
