Transform the rear profile of your Ferrari SF90 Stradale Coupe or Spider with this Carbon Fiber Rear Air Guide “Assetto Fiorano”, precision-engineered to integrate flawlessly with the factory bodywork while amplifying the car’s aerodynamic presence.

Although the SF90 is an exceptional design, its factory rear fascia can appear restrained when compared to Ferrari’s more aggressive hypercar lineage. This carbon fiber air guide addresses that by delivering a sharper, more purposeful look that enhances airflow management and visual depth—without compromising OEM elegance.

Manufactured from lightweight, high-strength carbon fiber, the diffuser is produced using an advanced vacuum infusion process, ensuring optimal rigidity, reduced weight, and a premium surface finish. After demolding, each unit undergoes rigorous inspection, tolerance verification, and quality testing before lacquer application. Final finishing includes hand and machine polishing, followed by waxing and sealing with high-content carnauba protection for lasting gloss and durability.

The design follows the original Ferrari lines precisely, resulting in a factory-integrated appearance that never looks aftermarket. It is the ideal finishing component for owners seeking a more aggressive yet authentic SF90 rear aesthetic.
