Zimmermann 100.3328.52 Disc Brake Rotor - Rear

Overview

The Zimmermann Sport Z disc brake rotor is built for drivers who want a drilled rotor design with coated corrosion protection and fitment-specific application coverage. Part number 100.3328.52 is engineered for rear brake service and uses a cross-drilled braking surface to help move water and brake dust away from the disc face.

Compatible with Audi TT and Audi TT Quattro rear brake applications, this rotor combines a 286 mm outer diameter, 12 mm disc thickness, and 65 mm centering diameter. The coated surface adds visual protection, while ECE R90 approval supports consistent replacement standards.

Key Features

• Cross-drilled, perforated rotor design for improved wet-surface braking response.
• Coated surface for added corrosion resistance and cleaner appearance.
• ECE R90 approved for regulated replacement use.
• Rear brake rotor with 286 mm outer diameter and 12 mm thickness.
• Part number 100.3328.52 for fitment verification and ordering.

Product Details

Zimmermann developed the Sport Z rotor using its brake rotor manufacturing experience and motorsport background. The design pairs high-quality cast material with a drilled braking surface to support water and dust evacuation, which is especially relevant in wet driving conditions. For Audi TT and Audi TT Quattro rear brake service, part number 100.3328.52 provides a direct rotor replacement with the dimensional and centering specifications needed for the listed applications.

This part cross-references Four Seasons (e.g., 14946, 197338) for the same application.

Common Issues This Rotor Can Address

• Brake vibration or uneven braking feel from a worn rear rotor.
• Reduced braking consistency in wet conditions.
• Visible rotor corrosion on the braking surface.
• Rotor wear that has reached minimum thickness limits.

Installation Notes

Verify PR code coverage before installation: 1KZ, 2ED, 1KJ, and 2EE are listed for the applicable Audi TT and Audi TT Quattro rear fitments. Confirm rotor dimensions, bolt pattern, and centering diameter against the vehicle before service. Part number 100.3328.52 should be matched to the rear axle application shown in the fitment data.

Quality Assurance

This rotor is ECE R90 approved and supplied with the certification note referenced by the manufacturer. Zimmermann also identifies the Sport Z line as a coated rotor range with anti-corrosion treatment for improved surface protection.
