Zimmermann 4M8 615 301 D Sport Z Coated Brake Disc Rotor

The Zimmermann 4M8 615 301 D is a premium replacement brake disc engineered to OEM specifications and manufactured by Otto Zimmermann GmbH, one of Germany's most respected brake component suppliers. Designed as a direct-fit replacement rotor, this disc delivers reliable stopping power and long service life for demanding everyday and performance driving.

Zimmermann brake discs are produced using high-grade grey cast iron with a balanced microstructure for consistent friction performance, superior heat dissipation, and reduced brake fade. The disc features Zimmermann's signature Sport Z coating — a zinc-based anti-corrosion treatment applied to all non-friction surfaces — protecting against rust and surface degradation from road salt, moisture, and environmental exposure without compromising braking efficiency.

Key Features:

• Direct OEM replacement — matches original equipment fitment and geometry
• High-grade grey cast iron construction for optimal friction and thermal stability
• Sport Z anti-corrosion zinc coating on hub and hat surfaces
• Precision-balanced to minimize vibration and brake pedal pulsation
• Internally vented design for enhanced cooling and fade resistance
• Manufactured to ECE R90 and ISO/TS 16949 quality standards
• OEM cross-reference: 4M8 615 301 D

Zimmermann's stringent manufacturing process ensures each rotor meets or exceeds the dimensional tolerances and performance requirements of the original equipment part, making the 4M8 615 301 D an ideal choice for a quality brake system restoration.
