matte black will only look good if you have US guys G35 spec fitment and stance. most guys in oz seem to have their nuts tightly locked away in their purses when it comes to these two qualities, so unless you're willing to break with the norm, just make yours look somewhat tasteful and leave it at that. Otherwise you'll be rocking a colour fad from two years ago on fail fitment and stance, and you'll just be someone who hasn't quite got it right.
Get the wheels, stance and fitment right, and rock matte black, and no one will dare to criticise your choice in colour, even if it isn't to their taste. In this day and age when tonnes of guys have done it better, even if they are in a different country, if you don't get the package completely right, someone will shoot you down for not measuring up.
