Description

The ADRO carbon fiber rear diffuser is an exterior body panel designed to enhance the appearance and aerodynamics of the G8x BMW M3 and M4. It features a more aggressive design and an expertly crafted aero profile, finished in stunning carbon fiber.

This diffuser includes sharpened rear winglets and a featured rain light for improved visibility in harsh conditions. It is constructed from prepreg carbon fiber, which helps to decrease vehicle drag and improve downforce.
