Ferrari have revised their halo-mounted mirrors for the Monaco GP after their previous design was deemed illegal by the FIA.
The team had revealed a radical design at the Spanish GP after the FIA had confirmed post-China that mirrors could be mounted on the halo.
However, Ferrari's design was deemed to give them too much aerodynamic gain with the FIA clarifying that halo-mounted mirrors must "provide a meaningful structural contribution to the mounting system" and "be mounted to the lower and/or inboard surface(s) of the mirror housing".
The Monaco-spec SF71-H features the mirrors still mounted to the halo but with its Spanish GP aerodynamic winglets removed.
-The FIA's clarification on halo-mounted mirrors-
'Whilst the FIA accepts that teams will legitimately design the mirrors, housings and mountings to minimise any negative aerodynamic effects they may cause, we believe that any aerodynamic benefits should be incidental, or at least minimal. In order to ensure this is the case all mountings must:
'a) Provide a meaningful structural contribution to the mounting system. If you use more than one mounting you may be asked to satisfy us, by way of a physical test, to demonstrate this.
'b) Be mounted to the lower and/or inboard surface(s) of the mirror housing.
'As the criteria for determining the eligibility of a mounting are to some extent subjective, the FIA would be available to discuss the legality of a new design before you introduce it in a race, to avoid wasting resource, time or money. For the sake of clarity, the various provisions made in TD/014-18 still apply for halo-mounted mirrors. The FIA expect to have full compliance with the present technical directive by the next race.
'The FIA do acknowledge that the rules currently in force with regard to mirrors are not perfect, and will strive to propose a more complete set of rules in terms of mirror position, mountings, visibility, etc. in the near future, with the aim to get a unanimous support for such changes for 2019.'
