2015–2021 Subaru WRX/STI Carbon Fiber Trunks

The best carbon fiber trunks for a 2015-2021 Subaru WRX or WRX STI are a full replacement carbon trunk lid in the style you prefer: an OEM-style lid for a clean factory look, a C-style or SS-style lid for a sharper profile, or a vacuum-infused OE-style trunk with garnish when you want weave choices. Check your year and model before ordering, and plan for trim transfer during the swap.

A carbon fiber trunk replaces the steel factory lid at the back of the car. A well-made lid should line up with the factory hinges, latch, and body gaps, and accept the trim your car uses. Shoppers choose between complete lids and smaller pieces such as a carbon trunk trim garnish, and many pair the trunk with our carbon fiber hoods range or the broader trunk category.

Seibon is a carbon fiber body specialist, and three of the seven listings here are theirs, which shows the depth they offer for this one application. WRX and STI owners can pick the C-style carbon fiber trunk lid for a more sculpted shape, an OEM-style lid for a factory silhouette, or the OEM-style version without an emblem recess for the cleanest rear view. That range makes Seibon the starting point for most shoppers on this platform.

VIS Racing builds carbon fiber hoods, trunks, and body panels across many Japanese platforms, and here it covers both ends of the job. Its SS-style carbon fiber trunk is a full replacement lid with its own distinct profile, while its carbon fiber trunk trim garnish lets owners add a carbon accent without replacing the whole lid. Offering both a complete panel and a finishing piece is typical of VIS, and it suits builders staging an exterior build over time.

JDMuscle is our house brand, and its entry is the OE-style vacuum-infused carbon fiber trunk with garnish, offered with multiple weave choices and marked special-order, no cancellation. ManSpeed rounds out the group with its own OE-style carbon trunk with garnish for 2015 and newer WRX/STI. How these panels compare with factory parts is covered in our guide to carbon fiber hoods and trunks.

Will a carbon fiber trunk fit my 2015-2021 WRX or STI?

These lids are listed for the 2015-2021 WRX/STI sedan, including product titles that name 2015-2020 fitment, so confirm the exact year range on the product page for your car before ordering. Sedan and hatchback rear panels are not interchangeable.

What is the difference between OEM-style, C-style, and SS-style lids?

OEM-style lids follow the factory shape in carbon fiber. The C-style and SS-style lids change the profile for a more aggressive look. Pick based on the rear-end style you want, then check whether the lid includes or reuses garnish and trim.

Is a carbon trunk a difficult install?

It is a panel swap on the factory hinges and latch, but carbon panels should be test-fitted and aligned carefully, and trim, garnish, and any wiring need to move over from the old lid. Many owners have a body shop handle final gap alignment.

Can I add carbon at the rear without replacing the whole trunk?

Yes. The VIS Racing carbon trunk trim garnish adds a carbon accent on its own, a smaller first step before a full lid.
