We should expect a significant change as this Imola package is highly sponsored by Krack and Fallows since the pre-season. Let's not forget Fallows pre season interview where he was saying that Aston will fight Red Bull this year. They are talking about a new floor, new aerodynamic elements, new diffuser and new suspension.
We will see how the car improves.
However we are already hearing impressive/scary number from Ferrari heavily inspired by Red Bull+ Ferrari had now the chance to pre test the package with the FIA test.
Mclaren already showed that the new package worked very well.
So for the first time we will be able to see if Aston solved the issue of the last year of incorrect data correlation between the data from the factory engineering and the race/car engineering
