I think the black grilles look better when the car has the M5Tech or MTech bumper. Those bumpers have a large black grille area underneath the kidney grilles, which makes the two grilles match better together. The stock grille (not sure what it's called) is more silver and it doesn't look as good.
Here's what I'm talking about but the shot wit the original grille doesn't have black grilles yet on it but hopefully you see my point.
