a little birdie told me that c/f IS LEGAL, but only if it is coated in some sort of.. stuff. that's what i am aware of. i think the coating prevents something. smashing? shards? shatters? splinters? big chunks? I dont know, i will ask for more details from the source tomorrow but yeah, i HEARD it was ok if it is coated in X product.
EDIT: a car which this mysterious 'source' owns recently passed the pits with a CF bonnet. it was approved and he (source) was making sure they picked up everything that wasn't legal coz he didn't want anything on his ride that wasn't legal. so he was checking it twice, basically.
Again, what the pits approve and what the cops will cannarie you for is different. I'm just passing on knowledge - correct or otherwise.
Like I said, details later if Ic an get them
