It combines high-carbon machining with a cross-drilled braking surface to support consistent braking performance in wet conditions and a cleaner rotor appearance.

Compatible With BMW 750i, 750Li, 760i, and 760Li rear brake applications, this rotor is engineered around the specified hub bore, bolt pattern, and thickness dimensions. The Zimmermann 150.3438.52 also includes ABE certification information supplied with the rotor.

Key Features

• Perforated brake disc design for improved water and brake dust evacuation
• Coated surface for added corrosion resistance and a cleaner visual finish
• High-carbon machining for stable rotor construction
• Rear rotor specification with 345 mm outer diameter and 24 mm thickness
• BMW fitment coverage for 750i, 750Li, 760i, and 760Li applications

Product Details

Zimmermann developed the Sport Z rotor using racing experience and long-term brake rotor manufacturing knowledge. The cross-drilled braking surface helps move moisture away from the disc face, while the coated finish addresses corrosion concerns and supports a more attractive appearance. Part number 150.3438.52 is a direct-fit rear disc brake rotor for the listed BMW 7 Series applications, including 2005-2008 BMW 750i, 750Li, 760i, and 760Li rear brake positions.

This part cross-references Dynomax 31723 for the same application.

Common Issues This Rotor Can Address

• Brake fade caused by moisture on the rotor surface
• Visible rotor corrosion and surface rust
• Uneven braking feel from worn rear rotors
• Reduced braking consistency during wet-weather driving

Installation Notes

Verify rotor dimensions, hub bore, bolt circle, and minimum thickness before installation. This rotor is specified for rear fitment on the listed BMW models, so confirm the vehicle year and application details against the fitment table before ordering. Professional installation and brake system inspection are recommended whenever rotors are replaced.

Quality Assurance

Zimmermann supplies this rotor with ABE certification information, and the product is offered with the manufacturer documentation supplied with the rotor.
