Zimmermann 400.3670.52 Sport Coat Z Perforated Brake Disc Rotor

The Zimmermann 400.3670.52 is a Sport Coat Z perforated brake disc designed as a direct replacement for Mercedes-Benz applications. Otto Zimmermann GmbH draws on decades of brake manufacturing experience — combining series-production expertise with motorsport-derived engineering — to deliver a rotor that outperforms standard OEM replacements.

Key Features:

• Perforated braking surface — cross-drilled holes continuously expel brake dust, water, and gases for consistent, fade-resistant stopping power in all weather conditions
• Coat Z anti-corrosion treatment — the entire rotor, including the hat and cooling vanes, is bathed in a protective coating to resist road salt, solvents, and other corrosives
• Internally vented construction — promotes heat dissipation and reduces thermal stress on the braking system
• High-quality cast materials — engineered for excellent wear resistance and long service life
• OEM-compatible fitment — replaces original Mercedes-Benz part numbers 164 421 0612 and 164 421 1512
• Ready to install — Coat Z treatment means no cleaning or prep is required prior to installation

This listing is for one (1) single brake disc. If replacing both sides on an axle, two units are required. For best results, replace brake pads at the same time and perform a proper pad bed-in procedure after installation to optimize performance and reduce noise.
