SINGAPORE (Reuters) -Formula One leaders McLaren will modify the rear wings on their cars after talks with the governing FIA at the Singapore Grand Prix following concern from rival teams. The British-based team went top of the standings in Azerbaijan last weekend but drew scrutiny of how the rear wing functioned at speed,

The FIA intervenes following intense scrutiny of McLaren's controversial rear wing design, which rival teams claim breaches aerodynamic regulations.

While investigations confirmed that McLaren's rear wing passed static load tests and was initially compliant with existing regulations, the FIA has mandated modifications.
