I don't think there are direct replacements, although some people do have them re-done in carbon fiber. Most people end up using vinyl wrap which is cheaper and removable.

 

Here's my liquid platinum sedan, gloss black window trim, gloss black spoiler, gloss black grille, gloss black Infiniti logo with debadged read, dual halos custom headlights with silver shroud and gloss black housing lowered on swift springs. Next I want to do full bolt ons and when I'm done with that wheels! Also was thinking about the roof wrap I seen a maxima my color done with a roof rack didn't look bad at all

 

Yeah not sure about the roof wrap. I think it looks good w/ white. Got a picture of your car I could check out? Sounds similar to what I want to build.
