A full carbon fiber replacement trunk lid with a molded-in ducktail — not a cap or overlay. Under 11 lbs versus the roughly 22 lb OE steel deck, bolt-on through factory hinges and latch with no cutting or drilling.
This is a complete rear deck lid, not a stick-on cover — the entire trunk is replaced with a carbon fiber panel that carries a ducktail-style spoiler molded directly into the lid. It follows factory body lines for an OEM+ rear-end look, and because it uses the OE hinge and latch locations, the trunk opens, closes, and seals the way it always did.
The panel is built from authentic 3K 2×2 twill carbon using a vacuum infusion process that optimizes resin distribution and minimizes trapped air for a smooth, consistent surface, then sealed under a high-gloss UV-resistant clear coat. At under 11 lbs against an approximately 22 lb OE steel trunk, it sheds meaningful weight off the rear while keeping a fully finished underside for factory hinge and latch compatibility.
What Sets It Apart
Full Carbon Replacement Lid
A complete rear trunk deck lid in real 3K 2×2 twill carbon fiber — a true replacement panel, not a stick-on cover.
Integrated Ducktail Spoiler
The ducktail-style spoiler is molded directly into the lid for an aggressive OEM+ rear profile with no add-on wing.
Vacuum-Infused Build
A vacuum infusion process improves resin consistency and reduces air pockets for a smooth, high-gloss surface.
Under 11 Pounds
Weighs under 11 lbs versus the roughly 22 lb OE steel trunk, trimming weight off the rear of the car.
Factory Hinge & Latch Fit
Reuses OE hinges, latch components, and mounting points with a finished underside for proper latch operation.
UV-Resistant Clear Coat
A high-gloss UV-resistant clear coat showcases the weave while resisting fading, yellowing, and oxidation.
