Zimmermann 150.3454.70 Disc Brake Rotor - Rear Right

Overview

Zimmermann Formula Z brake rotor 150.3454.70 is a two-piece, coated disc brake rotor built for high thermal and mechanical load. It combines a floating aluminum hub design with high-carbon machining to support stable braking performance and improved resistance to heat cracking.

Compatible With BMW applications including the Z4 and M3, this rotor is specified for rear right fitment and is suited to performance-oriented braking systems. Part number 150.3454.70 is also identified by cross-reference numbers used for the same application.

Key Features

• Two-piece brake disc construction for reduced stress under load.
• Floating aluminum hub design allows radial expansion during heavy braking.
• High-carbon machining supports heat resistance and consistent disc behavior.
• Coated surface helps resist corrosion and maintain a cleaner appearance.
• General ABE certification or ECE note supplied with the rotor.

Detailed Description

The Zimmermann Formula Z rotor 150.3454.70 is engineered for demanding braking conditions where heat management and dimensional stability matter. Its floating mounting design helps the disc expand radially under load, which reduces shielding effects and improves resistance to heat cracks. The two-piece construction and coated finish make it a practical choice for BMW brake systems that see elevated thermal demand, including BMW Z4 and BMW M3 rear right applications. Part number 150.3454.70 is a direct reference for this rotor, and the paired article number is 150.3453.70.

This part cross-references BBB Industries 17237 and Interchanges 24.0120-0222.2 for the same application.

What It Is Used For

• Replacing a worn or heat-stressed brake rotor.
• Addressing brake pulsation caused by rotor distortion.
• Improving resistance to thermal cracking under repeated braking.
• Restoring braking consistency in performance-focused BMW applications.
• Supporting corrosion resistance with a coated disc surface.

Installation Notes and Tips

Verify rear right fitment before installation. Confirm rotor dimensions, hub bore, bolt circle, and minimum thickness against the vehicle specification. This rotor is supplied with general ABE certification or an ECE note, so check local compliance requirements before service. Use the paired article number only when matching the opposite-side or companion application specified by the catalog.

Quality Assurance

Zimmermann Formula Z rotors are produced with a coated surface and floating hub design to support stable performance under high load. The rotor is supplied with general ABE certification or an ECE note, depending on market requirements.
