Before the racing weekend GP of France a new and stricter rule will be introduced or stress tests to check the flexibility of the rear wing. FIA however, by looking for a trick, she will test testing this weekend in Baku.
Mercedes he had made it clear before that I seemed to them GP of France too far to introduce new tests as it is supposed to have Red Bull in their view the benefit of a flexible rear wing here in Baku. It is after the defeat in Monaco Toto wolff threatened to file a protest if FIA will not take action already in the race Grand Prix of Azerbaijan. And apparently they were prayers of the German team obedient.
FIA namely, it placed on the rear wings of all racing cars yellow stickersto measure the amount of bending. These stickers (these are yellow dots) will be used as reference points when monitoring the various hind wings. That would ensure comparative material before the introduction of new tests. Teams whose back wings are too flexible, will have to perform technical adjustments before the next race in France.
