A full carbon fiber decklid with the ducktail already built in — swaps your S650 trunk for one clean dry-carbon piece that adds a lip without a bolted-on wing.
Dry Carbon · Integrated Ducktail · Direct Replacement

Instead of bolting a spoiler onto the factory trunk, this replaces the whole decklid with a single dry carbon fiber panel that has the ducktail molded right in. Cleaner look, no seams, no drilling a wing into your paint.
It is real pre-preg dry carbon under a UV clear coat, and it reuses your factory trunk hardware, latch, and lights. Subtle from the side, aggressive from behind.
Pre-preg dry carbon — lighter and tighter weave than wet-layup, finished in a UV-stable clear coat.
The lip is molded into the lid, so there is no bolt-on wing, no seam line, and nothing drilled into your paint.
Reuses the factory trunk hinges, latch, struts, and third brake light. Straight swap.
Kicks the decklid line up just enough to give the S650 a planted, aggressive tail.
EcoBoost, GT, and Dark Horse share the decklid — this fits all three.
Run the bare gloss carbon or paint to match — your call.
