From the Spanish Grand Prix onwards, the front wing of a Formula 1 car will be allowed to deflect a maximum of 10 millimetres (it is currently 15 millimetres) under load. A challenge therefore awaits the teams: one specification of front wings may be raced in the first part of the season, and a different one in the second. According to Christian Horner, Red Bull Racing’s team boss, there is a negative side effect to the mid-year rule change.
