The ducktail profile is one of the most recognisable and purposeful spoiler designs in motorsport — extending upward and outward from the boot lid edge to create a bold, sculpted rear silhouette that is immediately more assertive than a conventional lip spoiler. The high-gloss epoxy polished surface showcases the natural carbon weave finish and provides lasting protection against UV exposure, moisture, and surface degradation. Adhesive tape is supplied for a clean, no-drill installation with no permanent modification required to the factory boot lid.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine carbon fiber construction – autoclave cured using 3D design and CNC moulding for precise
