Your car looks great dude!! I love the all blacked look! The stripe would look OK, but it's still sweet looking! Either or. Maybe add in a silver one to go with your exhaust tips? Red with your tails too though!
Very nice. I say NO pinstripe, that defeats the whole purpose of going for the all black look (in my opinion). I love the way it looks. You should consider tinting the tails.
looks really clean. only thing i could think of other than what has already been said is the headlights. maybe smoked? i dunno, just something to get rid of that orange side marker
