Ferrari pushed the boundaries in Spain with their arrangement of halo-mounted mirrors. The FIA took a closer look and chose to outlaw them. The governing body has now issued a clarification to all teams, advising them of what will be acceptable in the future…

Ahead of the Azerbaijan Grand Prix, F1 teams were told they could mount mirrors on the halo to allow for better visibility. Ferrari opted to take advantage, adding their unique arrangement to the car in Spain.

Sebastian Vettel saw nothing wrong with what Ferrari had done, adding it improved his visbility. However, there was a feeling among rivals that the winglets Ferrari used in conjunction with the mirrors were being exploited primarily for aerodynamic gain, rather than visibility.

The FIA felt the arrangement broke the rules, and while they allowed the Italian team to keep it on the car for the remainder of the weekend, they told them to remove it for the upcoming race in Monaco.

The FIA accepted that the current criteria is “to some extent subjective” and on Wednesday afternoon sent a clarification to the teams, outlining what is allowed going forward, as well as making the governing body available to discuss new designs before they are introduced.
