Product Line Details

The Premium Xtra Cross Drilled UV Coated Rotor line by Brembo focuses on combining advanced rotor design with protective coatings to extend service life and maintain consistent braking performance. The cross drilled braking surface enhances heat dissipation and reduces brake fade, while the UV coating provides resistance against rust, making it suitable for Volkswagen models that require reliable and durable rotors.

Technical Description and Features

This disc brake rotor is made from grey cast iron, a material known for its excellent thermal conductivity and durability under high-stress braking conditions. The vented design allows air to flow between the rotor surfaces, improving cooling during operation. The cross drilled holes on the braking surface help to dissipate heat and gases generated during braking, which can improve stopping power and reduce brake fade. The UV coating protects the rotor from rust and corrosion, extending the rotor’s lifespan and maintaining performance over time. The rotor measures 256 mm in outside diameter with a height of 38.7 mm and a centering diameter of 65 mm, ensuring precise fitment on compatible Volkswagen models. Fixing screws are included to facilitate installation, and the rotor requires a torque of 110 Nm for proper mounting.
