Porsche 718 Cayman Boxster 982 GT4 Style Primer Black Rear Spoiler 2017-2019

Upgrade the rear styling and aerodynamic profile of your 2017–2019 Porsche 718 Cayman or Boxster with this GT4 style rear spoiler. Designed for 982 generation models, this performance-inspired exterior upgrade adds a more aggressive rear-end appearance while complementing the factory design language of the vehicle.

Styled after the GT4 performance package, this rear spoiler is engineered to enhance airflow and provide a more purposeful, motorsport-inspired look. Its shape follows the rear contours of the 718 platform for a clean OEM-style fitment that improves visual presence without disrupting the vehicle’s original proportions.

Constructed from reinforced polypropylene, this spoiler offers excellent durability, lightweight performance, and resistance to everyday road and weather conditions. Finished in primer black, it can be installed as-is or prepped and painted to match your vehicle for a more customized finish.
