FIA has recently closed the case of Red Bull's front bib height adjuster device. They have decided not to investigate past car setups the defending world champions used in order to discover whether they have altered front bib height before or not.
Right before the 2024 F1 US GP, the FIA made sure that no modifications were done to the front bib on any car between race sessions, particularly during Parc Ferme conditions.
Front bib is an aerodynamic element situated underneath the front wing and behind the front axle. It is also known as T-ray. Adjusting this part during Parc Ferme is not allowed because it could change the overall ride height of the vehicle.
