No it isn't aside of the side skirts, rear diffuser and front spoiler ... you could also add the mirrors (though not full CF) and a few other small parts like door handles and fuel door.
Also, not sure but in the picture the CF bonnet looks like wrap ... at least not the usual Ferrari pattern which is plain weave.
