The tweaks were trialled at a filming day Ferrari conducted at Fiorano earlier in the week where its F1 challenger ran alongside its Le Mans-winning Hypercar.
This was a shrewd move by the Scuderia, given that teams have less time to evaluate parts during free practice at the Red Bull Ring because it is a sprint event.
The changes that Ferrari have made are pretty extensive but mainly focus on the outboard section of the wing and endplate in order that the front tyre wake can be handled a little differently.
This also has the benefit of improving flow downstream for the revisions Ferrari introduced to its sidepods and floor at the Spanish GP.
