Well if you really care what I think, don't do it. Ive seen so many old rattle trap Mustangs, Cameros and Pontac pony cars blacked out, not to mention circa 80's, boxy, semi performance cars from Japan that I have come to loathe that look. I used to think high performance when I saw it, now I think, Rattle can restoration.
It's yesterdays look. A little bling tastefully done looks much hotter. Chrome the strakes, the grill, and leave the wing alone (not sure if you meant your Needwings intake or your spoiler) either way, leave it alone. If you have the cash put some Giovanni or other art work wheels on it.
YOU ASKED, MAX
P.S. you can't really chrome those items but you can get overlays
