Zimmermann 150.3434.55 Black Z Sport Brake Disc - Internally Vented, Slotted, High-Carbon

The Zimmermann 150.3434.55 Black Z is a high-performance sport brake disc engineered for drivers who demand superior stopping power on both the road and track. Developed by Otto Zimmermann GmbH using decades of experience in series-production and motorsport applications, the Black Z line features a utility-patent-protected groove pattern that sets it apart from standard and cross-drilled alternatives.

This disc is constructed from high-carbon cast iron and features an internally vented, slotted design with a protective anti-corrosion coating. The proprietary grooves are precision-engineered to expel water, heat, and gases rapidly from the friction surface, delivering faster brake response and consistent pedal feel under demanding conditions.

Key Features:

• Black Z Slotted Design: Utility-patent-protected groove pattern optimizes heat dissipation and improves braking power over cross-drilled alternatives
• Internally Vented Construction: Promotes airflow through the disc for continuous cooling during heavy brake use
• High-Carbon Cast Iron: Premium material formulation for reduced noise, vibration, and improved thermal stability
• Anti-Corrosion Coating: Protective surface finish reduces rust formation on non-contact areas
• OEM Dimensions: 348mm outer diameter × 30mm thickness — direct OEM replacement fit
• Bolt Pattern: 5×120mm, 6/5 hole pitch — compatible with OEM specifications
• ECE R90 Approved: Meets European brake component safety standards
