Carbon Fiber Rear Bumper Lip Diffuser for Porsche Cayman 718 16-18 by Stratec Systems

Enhance the rear-end presence and aerodynamic performance of your Porsche with the STRATEC™ Carbon Fiber Rear Diffuser, engineered specifically for the 2016–2018 Porsche 718 Cayman. Designed to integrate seamlessly with the factory rear bumper, this diffuser delivers a bold, motorsport-inspired look while maintaining a refined OEM-plus appearance.

Constructed from high-quality carbon fiber, the STRATEC™ rear diffuser is lightweight, durable, and precision-molded for exact fitment. Its sculpted fins and aerodynamic profile help manage airflow beneath the vehicle, improving rear-end stability and visual aggression without compromising daily drivability.

Designed to follow the factory bumper contours, this rear diffuser installs cleanly as a bumper lip upgrade, enhancing the Cayman’s rear profile with a lower, wider, and more performance-oriented stance. A UV-resistant clear coat protects the carbon fiber surface, ensuring long-lasting gloss, durability, and resistance to environmental wear.
