Seibon OEM-Style Carbon Fiber Trunk Garnish - 2014-2015 Honda Civic Si Coupe (FG4)
This is the panel on the upper rear section of your trunk, sitting beneath the factory Si wing. Stock, it's painted to match the car and it disappears. In gloss carbon it does the opposite, adding depth and texture right where the wing frames it. It's an affordable piece in a spot most people never think to change, which is exactly why it lands when someone notices it. Small mod, real impact.
Built To Take Your Factory Brake Light
Seibon designed this garnish with a dedicated spot for your OEM third brake light, so it transfers straight over during installation. That's what gives it genuine OEM fit and finish rather than looking like an aftermarket panel with a light stuck in it. The light itself isn't included, you're reusing your own, which is exactly how it should work.
Take your time getting the light out of the old garnish so you don't break the tabs, and confirm it's seated properly in the new one before you button everything back up.
Your Wing Comes Off For This
Plan for it before you start. Because this garnish sits beneath the factory Si wing, the wing has to come off to swap the panel. It's not difficult, but it's a step people don't expect, and it turns a quick job into an afternoon if you're not set up for it.
While the wing is off, take the chance to clean underneath it and check your mounting hardware. It's an area that collects grit and almost never gets attention, and you're already there.
Why It Works Under The Wing
The factory wing frames this panel, and that framing is what makes carbon look deliberate here instead of random. The weave shows through the gap under the wing and across the upper trunk, reading as depth and detail from behind and from above. It's the kind of thing that makes someone walking around your car at a meet stop and look closer.
It also pulls a build together. If you've already got carbon on the mirrors, a lip, or a spoiler, this fills in a spot most people leave painted and makes the rest of it look planned rather than piecemeal.
OEM Shape, Straightforward Fit
This is a direct OEM-style replacement shaped to the FG4's upper trunk contours, so it follows the factory lines exactly and sits flush with everything around it. No fabrication, no trimming, no fighting alignment. Beyond pulling the wing and moving your brake light across, there's nothing complicated about it.
Real Carbon With A Gloss Finish
Seibon has been doing this long enough that their weave quality is the reason people pay for the name. This is genuine carbon fiber under a gloss clear coat, not hydro-dipped plastic or a vinyl wrap. The weave is visible and consistent across the panel, which is what makes it match other carbon on the car instead of looking almost right. It's built to handle weather, road grime, and daily driving rather than clouding over after a season.
Keep It Looking New
Treat the finish like paint. Keep it clean and give it wax or a ceramic spray a couple of times a year. UV is what dulls and yellows carbon clear coat over time, and this panel sits flat and takes direct sun all day. A few minutes of upkeep a year keeps it looking like it did on install day.

Pull the wing, transfer your brake light, and put carbon where everyone else has paint.
