Not really sure. It’s supposed to be a copy of the DC spoiler, but honestly it looks pretty thin. On the pictures of the backside I don’t even really see a good way to mount it.
The coverage is important, and it looks like it will cover more area than the Camaro spoiler. But the more area it covers the more air pressure it will have to withstand. I haven’t seen that one in person, but it looks like it will be hard to mount in a way it will be strong enough to actually hold up at higher speeds.
