Ferrari first introduced these at Imola, to help extract the heat generated by the rear brakes. The lip of the shield separates the hot airflow from the rim walls, helping to stabilise tyre pressure by limiting the effect of the brake heat. In Turkey the concept is pushed further, with a wider lip section reducing the size of the central air vent. This improves air extraction still further by decreasing turbulence generated by airflow close to the wheel. It also slightly improves aerodynamic efficiency in this area.

This evolution was tested before the French Grand Prix, but only used for the first time in Turkey. The barge-board profile has changed dramatically, especially the top of the shields. These now feature a clear saw-tooth profile towards the rear, while the front edge has lost its rounded top corner in favour of a sharp, vertical edge (see detail). Another addition is the small, vertical fin (lowermost arrow) right in front of the main profile, connected to the horizontal turning vane, which helps improve airflow management in this area. These changes continue the detailed refinement of the aero package ahead of the forthcoming Monza race, where aero efficiency on the long, fast straights is paramount.
