Zimmermann 400.5513.70 Coat Z Coated Brake Disc / Rotor

The Zimmermann 400.5513.70 is a premium Coat Z anti-corrosion coated brake disc engineered to OEM-equivalent standards. Zimmermann's Coat Z surface treatment covers the entire rotor — including the hat, friction faces, and internal cooling vanes — providing comprehensive corrosion resistance without requiring removal of the coating prior to installation.

Key Features:

• Coat Z Anti-Corrosion Coating: Zinc-based protective coating applied to the full rotor surface eliminates rust formation at the hub and maintains visual appearance over time
• High Carbon Content: Proprietary high-carbon grey iron formulation delivers superior thermal resistance and long service life comparable to OEM specifications
• OEM-Equivalent Fitment: Manufactured to exact OEM dimensions and tolerances for direct, no-modification installation
• Ready to Install: Coat Z coating is fully functional upon mounting — no break-in coating removal needed
• European Manufacturing: Produced in Germany under strict quality management systems by Otto Zimmermann GmbH
• Vented Design: Internal venting promotes heat dissipation to reduce brake fade under repeated or heavy braking

Zimmermann is a leading OEM-supplier-grade brake disc manufacturer whose products are trusted as direct replacements across major European vehicle platforms. The 400.5513.70 brake disc / brake rotor is sold as a single unit and should be replaced in axle pairs for balanced braking performance. A proper bed-in procedure is recommended after installation to maximize pad-to-rotor contact and braking efficiency.
