F1’s regulations limit the amount of flexibility permitted, but teams try to find ways to maximize this to improve performance.

Formula One leaders McLaren have modified the rear wings on their cars at the Singapore Grand Prix after talks with the governing FIA following concern from rival teams.

While the McLaren wing passed the FIA's standard static flexibility checks, Marko pointed out that the regulations also prohibit significant bending during actual racing conditions. "That wing bends in the race," he claimed, "and it gives them an advantage."
