Enhance the rear-end styling and aerodynamic character of your Porsche 981 with the STRATEC™ Carbon Fiber GT4 Style Rear Diffuser, engineered specifically for the 2013–2015 Porsche Cayman and Boxster. Drawing inspiration from GT4 motorsport design, this rear diffuser delivers a more aggressive, track-inspired appearance while maintaining a clean OEM-plus fit and finish.
Constructed from high-quality carbon fiber, the STRATEC™ rear diffuser is lightweight, durable, and precision-molded for accurate alignment with the factory rear bumper. The GT4-style fins are designed to help manage airflow underneath the vehicle, contributing to improved rear stability and a more purposeful stance without compromising everyday drivability.
Designed as a direct bumper diffuser lip upgrade, this component follows the factory bumper contours for seamless integration. A UV-resistant clear coat protects the carbon fiber surface, ensuring long-lasting gloss, durability, and resistance to environmental wear.
