Zimmermann 100337820 Coat Z Front Brake Rotor 338x30mm

The Zimmermann 100337820 is a premium front disc brake rotor engineered to meet OE specifications for select Audi applications. This high-performance rotor features a 338mm outer diameter with a 30mm thickness, designed specifically for vehicles equipped with heavy-duty brake packages.

Coat Z Anti-Corrosion Technology:

This rotor features Zimmermann's proprietary Coat Z protective coating, which prevents rust and corrosion formation on the hub and cooling vanes. The water-based coating is heat-cured during manufacturing to remove all oil residue, creating a durable surface that resists road salt, solvents, and other corrosive materials. This coating extends rotor life, maintains an attractive appearance throughout its service life, and provides immediate functional capability without requiring coating removal before installation.

German Engineering and Quality:

With over 50 years of brake manufacturing experience, Zimmermann produces all rotors in Germany using high-carbon grey cast iron with flake graphite composition. The material compound is precisely matched to OE specifications and enhanced with supplements including copper, molybdenum, titanium, and carbon materials for superior durability and thermal resistance. Each rotor features directional curved vane design that improves airflow and cooling efficiency.

Key Features:

• 338mm outer diameter x 30mm thickness for heavy-duty braking applications
• Coat Z anti-corrosion coating on hub and cooling vanes
• High-carbon grey cast iron construction for excellent wear resistance
• Directional vented design for optimal heat dissipation
• Manufactured in Germany to DIN EN ISO 9001:2008 and ISO TS 16949 standards
• Meets or exceeds OE specifications for dimension and material quality
• Direct OE replacement design for proper fit and function

OE Cross-Reference Numbers: 8W0615301AB, 8W0615301P, 80A615301F, 80A615301A

Zimmermann rotors are engineered as direct OE replacements, ensuring proper fitment and braking performance. When replacing brake rotors, it is recommended to replace brake pads simultaneously and to replace rotors in pairs (both front or both rear) for balanced braking performance.
