Carbon Fiber Trunk OEM Style for Subaru WRX 4DR 2015-2021
OEM Style Carbon Fiber Trunk | 2015–2021 Subaru WRX & STI
Maintain the classic, clean lines of your VA chassis while reaping the benefits of high-end materials. Our OEM Style Carbon Fiber Trunk is the perfect choice for the "stealth" enthusiast—someone who wants the weight savings and premium look of carbon fiber without the aggressive "high-kick" spoilers found on other designs. It mirrors the factory silhouette perfectly, providing a refined, high-tech upgrade to your 2015–2021 WRX or STI.
Built to a Higher Standard
Marine-Grade Epoxy Resin To ensure your trunk looks as good in five years as it does on day one, we use a high-performance Marine Base Epoxy Resin. Unlike standard clear coats that can become brittle or "cloudy" under the sun, this resin is designed to handle intense UV exposure and thermal expansion. It creates a deep, durable bond with the carbon fabric, keeping your trunk's finish crystal clear and structurally sound through every season.
3K Twill Carbon Fiber We use authentic 3K Twill Weave carbon fiber, vacuum-infused for an optimal resin-to-fabric ratio. This manufacturing technique eliminates excess weight and air pockets, resulting in a lightweight component that doesn't sacrifice strength. You get that iconic "wet-look" finish and a consistent weave pattern that perfectly complements the Subaru body lines.
Important Fitment & Setup Notes
JDM Spec Plate Mounting This trunk is a JDM (Japanese Domestic Market) spec unit. Because the mounting standards in Japan differ from those in the US, the pre-set holes will not align with a standard US license plate. You will need to drill an additional hole to properly mount your plate. It’s a simple adjustment, but we always recommend a quick test-fit before final installation.
OEM Spring Warning Because this carbon fiber trunk is drastically lighter than your original steel unit, do not reuse the factory trunk springs or struts. The stock springs are under heavy tension designed to lift a steel lid; if used with carbon, they can cause the trunk to "snap" open violently, which may lead to stress cracks or hinge damage. Removing these springs is essential for the longevity of the part.
