I'm hoping to get a CDC chin soon and I love the look of the chin with the carbon diffuser under it. I thin apr makes the ones I'm thinking about. I just want to know how they are designed. Is it a flat piece or does it contour anywhere? If it's flat can't I just lay some carbon on a peice of glass and make my own pretty easily?

 

Apr rear diffuser is actually contoured. It is a lot more complex than it looks. It is a nice piece though.
