I've been looking for something like this for ages, just wanted a little upward flick on the spoiler but didn't know how I was going to do it, the fact that its carbon is even better although it wont tie in with my carbon-kevlar bonnet.
That is proper silly money though for what it is, I would love to have a closer look at one in the flesh as I could probably replicate it in carbon but would need one to make a mould from it. The way they've done it is clever though as most "wet" carbon parts have a great resin finish on one side but not the other, they must make a single skin front and a back and bond them together or something...
