Eh, i've been considering getting a lot of CF goodies for my car....they make whole doors in CF, as well as the bonnet and the tailgate - substantial weight savings! :)

5kg each!!! 5!!! Consider if you will, each door on its own weighs over 4 times that much :D
Of course, these would be sprayed the same colour as the car, to be unnoticeable from stock parts ;)
