Does anybody know the rules (from either the technical or sporting regulations) on how a team is allowed to change the angle of attack of the front wing?
In theory they are allowed to change the aero however they want during the race. The race is not run under parc ferme rules (mostly, somebody will come by and tell what the exceptions are). The only rule is that the driver himself is not allowed to do so, which limits effectively the moments a car can be changes to the pitstops. You can guess that for instance lowering the car Is not possible due changing suspension takes at least a hour. Equally throwing on a different wing too costs too much time relative to the gains of such a change.
However, teams can tear off gurney tabs to make quick changes.
