Technical Details and Specifications

This Zimmermann disc brake rotor features a two-piece design combining a high-carbon alloyed braking surface with an aluminum hub. The floating hub design allows for thermal expansion and contraction, reducing the risk of warping under heavy braking conditions. With an outer diameter of 334 mm and a thickness of 32 mm, it meets the precise requirements for Mercedes-Benz AMG models such as the C43 AMG, CLK55 AMG, and E55 AMG. The rotor’s bolt hole circle measures 112 mm, accommodating a 6/5 hole arrangement, and the hub bore diameter is 67 mm. The coated surface enhances corrosion resistance, extending the rotor’s service life. The minimum thickness of 30.4 mm ensures safe operation within manufacturer tolerances.

Compatible Vehicles and Applications

This disc brake rotor is specifically compatible with the following Mercedes-Benz AMG models:

• Mercedes-Benz C43 AMG
• Mercedes-Benz CLK55 AMG
• Mercedes-Benz E55 AMG
