The first race after the summer break always provides us with the opportunity to see new parts on the cars, especially as Spa is quite a unique challenge. Long straights combined with a tricky second sector demands a compromise between drag reduction and downforce.
The second is wing more specifically keyed at low downforce circuits, meaning it was only be tested in Spa ahead of the lower downforce configuration required for Monza. The cascade element that is ordinarily used to direct airflow up and around the front tyre is replaced by two vertical fins, these two are used for a similar purpose but their effect will be reduced. Again this is a response to the need for less drag over these next few races.
