Description
Enhance the rear profile and aerodynamic performance of your Porsche Cayman GT4 981 with the AF-1 Rear Diffuser (GFK). Designed for enthusiasts who demand both aggressive styling and reliable durability, this 1-piece rear diffuser delivers improved airflow management while maintaining a factory-quality fit and finish.
Manufactured using advanced Glass Fibre Komposite (GFK), this diffuser is constructed from milled and cross-woven fibres through a proprietary process that ensures exceptional strength, flexibility, and long-term durability. The result is a lightweight yet impact-resistant component engineered to withstand daily driving and spirited performance use.
Each Aero Function Glass Fibre Komposite product comes standard with a double-layered signature gray primer. This reduces preparation time before paint while ensuring a smooth and superior final finish. Where applicable, the diffuser includes a honeycomb black mesh grille for added visual depth and airflow optimization.
Built under a strict Five-Stage Aero Function Quality Control Assurance Manufacturing System, every unit is carefully inspected to meet high standards of precision and consistency. The product is also backed by a 3-year limited Aero Function manufacturer’s warranty and shipped using an extensive Ship-Safe packaging and protection system to reduce the risk of freight damage.
