The Yaris hood weighs close to nothing. So in this case it's most definitely for looks than weight-saving. With that being said, I haven't seen/heard of any Yaris in Australia with a CF Hood. Goodluck with it! Make sure you post pics once you have 'em on.. :) Just an idea, if you're not looking for weight-saving (which in this case is close to nothing), then may I suggest doing a carbon fibre vinyl wrap on your stock bonnet? That way you get the look without the expensive price tag of a CF hood.
