There are no legal carbon fibre bonnets at all as far as i am aware. The only thing close to it is the blits fibre glass bonnets.
From the sounds of it your more so after the bling bling look at me aspect of it but honestly its not worth it. When you get pulled over, and you will, you will get a defect notice, a fine and lose points on your license too. Then you will have to fork out to get a standard bonnet anyway. Your better off just buying a standard one to begin with.
