In introducing new bargeboards, the team has added a horizontal vane around halfway up these surfaces to better guide the flow. The footplate is separated into four surfaces in order to better control the migration and shape of the airflow under the car's floor too, hopefully improving rear end stability - an issue the drivers have reported in the opening races.
