VERUS ENGINEERING A0150A Rear Diffuser Kit (Carbon) for PORSCHE Cayman GT4 (981)

Description VERUS ENGINEERING A0150A Rear Diffuser Kit (Carbon) for PORSCHE Cayman GT4 (981)

The VERUS ENGINEERING A0150A Rear Diffuser Kit is developed to enhance rear aerodynamic performance of the Porsche Cayman GT4 (981) by increasing downforce while minimizing drag. Designed using advanced scan data, CAD modeling, and ANSYS Fluent CFD analysis, the diffuser delivers functional aerodynamic gains while maintaining a factory-integrated appearance.

The diffuser assembly combines autoclave-cured carbon fiber main planes with durable polyurethane strakes to ensure structural rigidity and long-term durability. The system mounts directly to existing chassis locations using multiple sheet metal brackets, requiring no drilling or fabrication for installation. The diffuser geometry is designed to follow the factory rear bumper lines for seamless integration.

• Increases rear downforce while reducing aerodynamic drag
• CFD-optimized using ANSYS Fluent for improved underbody airflow management
• Carbon fiber diffuser planes with replaceable polyurethane strakes
• Modular design allows addition of a flat underbody panel for increased performance
• Bolt-on installation utilizing factory chassis mounting points

Specifications:

• Diffuser Material: 2x2 twill autoclave-cured carbon fiber, 1.5 mm thickness
