hey h-t,
i don't know what exactly the part it is so i'm going to try to describe it...not the whole trunk carbon fiber but only where near the license plate goes piece..i think its looks nice

also do you know where i can find them,thank

 

you're referring to the black plate that sits behind the license plate that sits in the concave of the trunk. I don't know what the "official" name of it is, however i've never seen that done in carbon fiber outside of a full CF trunk.

 

That's called a license plate garnish.

I don't know where to find carbon fiber ones.
