- ECE R90 approved inspection tag for regulated replacement standards.
Product Details
The Zimmermann 100.3386.70 rotor measures 349 mm in outer diameter, 34 mm thickness, and 57 mm height, with a 32.0 mm minimum thickness. It uses a 112 mm bolt hole circle, 68 mm centering diameter, and a 6/5 hole arrangement. This rotor is a direct-fit brake service component for Audi A7 Sportback, Audi A8 Quattro, and related front applications where the original brake disc specification calls for this size and configuration.
This part cross-references Audi 4M0 615 301 Q for the same application.
Common Uses
- Restores braking performance when the original rotor is worn below service limits.
- Addresses brake pulsation caused by rotor thickness variation or surface wear.
- Replaces a scored or heat-affected front brake disc.
- Supports proper brake pad contact when the existing rotor surface is uneven.
Installation Notes
Verify rotor diameter, thickness, bolt pattern, and centering diameter before installation. Confirm front-position fitment against the vehicle’s brake specification and inspect pads, caliper condition, and hub surfaces during service. The coated finish should be handled carefully during installation to avoid unnecessary surface damage.
Quality Assurance
Zimmermann identifies this rotor with ECE R90 approval, indicating compliance with recognized replacement brake disc standards. Part number 100.3386.70 is also associated with Zimmermann 100.3386.75 as a cross-reference within the same rotor family.
