Zimmermann 400.3648.54 BLACK Z Slotted Vented Coated High-Carbon Brake Disc Rotor 330mm

The Zimmermann 400.3648.54 BLACK Z is a premium high-performance brake disc rotor engineered for drivers who demand superior stopping power and long-term durability. Measuring 330mm in diameter and 32mm in thickness, this internally vented, slotted, and fully coated rotor is manufactured from high-carbon cast iron and designed to meet or exceed OEM performance standards.

Key Features:

• Internally Vented Design: Promotes continuous airflow through the rotor to dissipate heat efficiently and maintain consistent braking performance under demanding conditions
• Patented Slot (Groove) Design: Derived directly from motorsport experience, the precision-machined slots channel away water, gas, and brake dust to reduce brake fade and ensure reliable pedal feel
• High-Carbon Material: Enhanced carbon content in the cast iron improves resistance to thermal stress and mechanical wear, extending rotor service life
• Coat Z™ Anti-Corrosion Coating: Full-surface protective coating prevents rust and corrosion, keeping the rotor looking and performing like new — even during extended storage or wet-weather use
• Specifications: Diameter: 330mm | Thickness: 32mm | Bolt Pattern: 5x112 | Hole Configuration: 8/5
• OEM-Grade Fit: Manufactured to precise tolerances for a direct, no-modification-required installation
