Lewis Hamilton says the introduction of a new rule clamping down on front wing flexibility at the Spanish Grand Prix was "a waste of money".Governing body the FIA imposed a stiffer load test on front wings to try to limit the amount teams could exploit their movement on track for aerodynamic advantage.

McLaren has still dominated in Barcelona with Oscar Piastri taking pole position for Sunday's Spanish Grand Prix.

With a 1000N load applied to either side of the front wing, the flex tests only permit a maximum of 10mm of deflection, down from the previous benchmark of 15mm. This has prompted teams to strengthen their wings, although many of those changes will largely remain structural.
