“What we don’t want to see is that, at the joint of, let’s say, a rear beam wing to an endplate that it’s decoupled in any way such that it can rotate about a pivot or it can move laterally or up and down,” said then-FIA single-seater director Tim Goss.
“So we’re saying that you can’t have very localised motion of one component relative to another. The assembly can move as a whole body but we don’t expect to see parts of it being able to translate relative to others.”
