Zimmermann 400.5566.52 Perforated Internally Vented Brake Disc Rotor 354mm

The Zimmermann 400.5566.52 is a premium perforated, internally vented brake disc engineered to meet the precise braking demands of high-performance vehicles. Measuring 354mm in outer diameter and 32mm in thickness, this rotor is built to exacting OEM tolerances with a 5-hole, 5×130mm bolt pattern for a secure, factory-correct fitment.

Featuring Zimmermann's signature Sport perforation, the cross-drilled surface continuously evacuates heat, gases, and brake dust from the rotor-pad interface. This keeps the braking system operating at peak efficiency and reduces fade under repeated heavy stops. The internal venting channels provide additional thermal management, dissipating heat rapidly and maintaining consistent pedal feel.

Key Features:

• Outer Diameter: 354mm
• Disc Thickness: 32mm
• Bolt Pattern: 5-hole / 5×130mm
• Construction: Internally vented with perforated (cross-drilled) braking surface
• Coating: Coat Z™ anti-corrosion surface treatment for extended service life
• Material: High-quality cast iron with high-carbon formulation for superior resistance to wear and thermo-mechanical deformation
• Sold individually — replace in pairs per axle for balanced braking performance

Zimmermann brake discs are manufactured to strict quality standards and are a trusted OEM-quality upgrade. The Coat Z™ anti-corrosion coating protects the disc hub and non-braking surfaces from rust and corrosion, ensuring a clean appearance and long service life. For best results, replace brake pads at the same time and always install rotors in matched pairs per axle.
