Yes that form 400/01 is the bane of my existence. Why oh why do they feel the need to be secretive about the damn technical regulations?

For what it's worth I just asked craig scarborough on twitter what he thought of the mirror wings and he said they're probably lousy, very high drag and little downforce. So maybe they got rid of them for that reason.
