Audi RS6 & RS7 C8 FI-1 Pre-preg Carbon Fibre Rear Diffuser by FORM (2020+)

The FORM FI-1 Pre-preg Carbon Fibre Rear Diffuser is an exclusive design created by Form Industries for the Audi RS6 C8 Avant and RS7 C8 Sportback, engineered to replace the factory lower rear bumper insert with a purpose-built carbon fibre performance piece. The kit includes a pair of integrated rear winglets — one either side — that extend the diffuser's visual and aerodynamic effect along the lower rear quarter. The images in this listing show the prototype kit that AUTOID fitted to a customer vehicle and returned to Form with structured feedback on fitment, integration with the factory quad exhaust arrangement, and surface finish — ensuring the production piece meets the standard demanded by the car. Autoclave-cured pre-preg construction gives the diffuser and winglets the structural rigidity and flawless gloss finish these cars demand.
