I'm cheering for McLaren so I hope they have a new diffuser ready to go.
It still amazes me that all these big teams didn't start working on a similar diffuser over a month ago when testing started.
Now they are crying foul and are standing there with their pants down.
That being said, I don't think McLaren has anything to lose and they should go for it if they got it.
However, I read an article that said that changing the diffuser wasn't so simple as MUCH of the car's aerodynamics needed to be changed to have it work properly.
That might be the reason why so many big teams didn't pursue it yet, it's because it's more complicated to implement than it appears on the surface (or underneath I should say, haha).
