Zimmermann 460.1577.20 Disc Brake Rotor

Brake Rotor Overview

Zimmermann 460.1577.20 is a perforated disc brake rotor with a coated surface for corrosion resistance and a cleaner appearance. It is built to OE-equivalent dimensions and material quality, with ECE R90 approval for the listed application.

Fits 2010-2013 Porsche 911, N/A. This rotor is a direct match for the specified fitment and uses a 350 mm outer diameter, 34 mm thickness, 32 mm minimum thickness, 98 mm hub bore, and 130 mm bolt circle.

Key Features

• Perforated brake disc design for consistent braking performance.
• Coated surface helps resist corrosion and maintain appearance.
• OE-equivalent construction based on manufacturer-specified dimensions and material quality.
• ECE R90 approved for the listed application.
• Part number 460.1577.20 for identification and ordering.

Detailed Description

Zimmermann 460.1577.20 is a disc brake rotor engineered to match the original part specification for the Porsche 911 application shown here. The perforated design and coated finish make it a practical replacement when the original rotor is worn, scored, or below service limits. The rotor’s 350 mm diameter, 34 mm nominal thickness, and 32 mm minimum thickness provide the dimensional reference needed for proper service selection. The paired article number is 460.1576.20, and the part number 460.1577.20 is also cross-referenced as 460.1577.00 for related applications.

Zimmermann’s standard rotor range is produced to manufacturer-defined dimensions and material quality, and the brand’s coated rotor line has been available since 2008 for improved corrosion resistance and appearance. For Porsche 911 brake rotor replacement needs, this part offers a specification-driven option that aligns with the listed fitment.

Common Replacement Reasons

• Brake pulsation caused by rotor wear or thickness variation.
• Scoring, grooves, or heat checking on the braking surface.
• Corrosion on the rotor face or hat area.
• Rotor thickness at or near minimum service specification.

Installation Notes

Verify rotor dimensions, hub bore, bolt circle, and brake disc type before installation. Clean the hub mounting surface and inspect related brake components for wear before fitting the new rotor. Confirm the vehicle application against the listed fitment for the Porsche 911, and use the part number 460.1577.20 to match the correct rotor specification.

Quality Assurance

This rotor carries ECE R90 approval and is manufactured to OE-equivalent standards for the specified application. Zimmermann’s standard brake rotor program is built to match manufacturer-defined dimensions and material quality.
