Description

The Bayson R GT4 Style Rear Diffuser is an aftermarket component designed to enhance the aerodynamic performance and aesthetic appeal of the Porsche 718 Boxster and Cayman models from 2017-2025. Its GT4-inspired styling adds a sleek and aggressive visual upgrade to the rear of your car, complementing its sporty design. The product includes holders for Parking Distance Control (PDC) sensors, offering versatility during installation. Installation hardware is included with this rear diffuser. However, installation instructions are not provided, and professional installation is highly recommended. The material will require prepping for paint before application to achieve a seamless finish.
