I don't know. At first glance, I don't like them. It dosen't look ricey, per se, but it does distracts a little bit. When I look at the picture, I immediately look at the vents. haha. And that's a coupe too. Imagine putting it on a convertible. In my opinion, when you have your top down, it'll look 'classy' in the back and 'agressive' in the front. You need to put something in the rear to complement the hood.
All in all, though, it's your money. Spend on what looks good to you. There's bound to be a single hater out there.
