Porsche Cayman GT4 Lightweight Bucket Seats, Genuine Full Carbon Fiber Buckets
Upgrade your build with a genuine set of Porsche Cayman GT4 lightweight bucket seats, the factory-optional full carbon-fiber buckets that transformed the GT4’s cabin from sporty to full-on track weapon. Offered as a rare, high-cost option on both the 981- and 718-generation Cayman GT4, these seats were never standard equipment, which makes a genuine take-off pair a serious find for anyone restoring, racing, or building out a Porsche-powered project.
Unlike the standard Adaptive Sport seats fitted to most GT4s, these shells are molded from carbon-fiber reinforced plastic (CFRP) for real weight savings over each corner, while still delivering the aggressive bolstering and low, fixed seating position that make the GT4 feel so connected on track. They’re a direct fit into a compatible GT4 chassis and a standout upgrade for other Porsche builds with the right mounting hardware.
