The company that produces the carbon fiber removable license plate bracket for the C6 ZR1, GS and Z06 is working on a design for the new C7.
I don't know what stage in the design process they are at, but if it is like the C6 version, it's going to be nice. I have one for my ZR1 and it's great! I personally like the way it sits lower on the facia and air flow is not a problem at all. I put it on when I drive and take it off when I am at home or at shows. It is super light and the carbon fiber pattern matches the front spoiler perfectly.
I trust the company will be looking for testers, as they did for for the C6 version and they gave a free bracket to the tester for their help.
Here is a video of the C6 one in action.
