Red Bull’s Christian Horner revealed that Red Bull and Ferrari were challenging the legality of the wing, after a gap was added to stall the air, therefore gaining a speed advantage.
It was later revealed that Ferrari weren’t particularly bothered by the wing after McLaren discussed the matter with Stefano Domenicali.
McLaren have though decided to take a contingency rear-wing to Bahrain just incase the FIA’s technical delegate, Charlie Whiting deems the current spec wing ‘illegal’.
“We’re not taking a radically different package, but you just never know what the stewards are going to do on the day,” McLaren’s Managing Director, Jonathan Neale said.
“We get the best advice we can from the FIA in the interests of transparency. If the stewards decide on a different course of action though it’s still our duty to go racing, so we have a contingency, but I wouldn’t put much effort into it.”
Neale added: “There’s nothing untoward about it though – we’re quite confident the car is legal.”
