Detailed Product Features and Specifications

This Brembo rotor is constructed from high carbon steel, which provides enhanced thermal conductivity and resistance to warping under high-stress braking conditions. The cross drilled braking surface improves water and gas dissipation, reducing the risk of brake fade during aggressive driving or in wet conditions. The rotor’s vented design allows air to flow between the rotor faces, further aiding in heat dissipation and maintaining consistent braking performance.

The UV coating applied to the rotor surface offers protection against rust and corrosion, extending the rotor’s service life and maintaining its structural integrity. With an outside diameter of 345 mm and a centering diameter of 68 mm, this rotor is designed to fit specific Audi models precisely. The rotor thickness ranges from a nominal 29.5 mm to a minimum of 28.2 mm, ensuring compliance with manufacturer specifications for safe operation.
