Zimmermann 150.3434.55 Disc Brake Rotor - Front or Front Right

Overview

Zimmermann Black Z is a slotted disc brake rotor built for BMW applications that need strong braking performance and corrosion resistance. Part number 150.3434.55 combines a coated surface with high-carbon machining and a grooved braking face for consistent stopping behavior in wet conditions.

This rotor fits select BMW 528i, 535i, 550i, 650i, 525i, 545i, and 645Ci applications in front positions, including one front right fitment. If you are replacing a BMW brake rotor with the same 348 mm x 30 mm specification, 150.3434.55 is the relevant match to verify.

Key Features

• Slotted brake disc design for improved dust and water evacuation.
• Coated surface helps resist corrosion and maintain appearance.
• High-carbon machining supports stable braking performance.
• 348 mm outer diameter with 30 mm thickness.
• ECE R90 homologated; no registration required when homologation applies.

Detailed Description

The Zimmermann Black Z rotor is engineered with a grooved braking surface and quality cast materials to support dependable braking under demanding conditions. The coating adds anti-corrosion protection, while the slot pattern helps clear brake dust and moisture from the contact area. Part number 150.3434.55 is a direct fit for multiple BMW front brake applications, including 2010 BMW 528i, 535i, and 550i front fitments, plus 2004-2005 BMW 545i and 645Ci front fitments. It also cross-references Monroe Shocks & Struts 18007 for the same application.

Zimmermann’s Black Z line focuses on rotors with a performance-oriented surface treatment and broad vehicle coverage. For BMW brake rotor replacement work, 150.3434.55 is a fitment-specific option that should be matched to rotor diameter, thickness, and hub dimensions before installation.

What It Helps Address

• Brake pulsation caused by worn or out-of-spec rotors.
• Reduced braking consistency in wet conditions.
• Corrosion on exposed rotor surfaces.
• Noise or uneven contact from damaged braking surfaces.
• Replacement needs for BMW front brake service.

Installation Notes

Verify rotor diameter, thickness, hub bore, and bolt pattern against the vehicle before installation. This rotor is listed for front applications, with one front right fitment noted in the catalog data. Confirm the paired article number 150.3434.54 when servicing the opposite side or matching components.

Quality Assurance

Zimmermann states that the Black Z rotor line is ECE R90 homologated, and the product is noted as not subject to registration when that homologation applies. Part number 150.3434.55 is built to the listed dimensional and material specifications for the confirmed BMW fitments.
