Ferrari 248 F1- rim shields 25 August 2006
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.
