The reason i know webber isnt running light is that in Quali 2 he was only a tenth off fastest, eventually ending up 3rd in that session and it doesnt take a genius to figure out that everyone was out there on fumes trying to get into Quali 3...
So the car, and more importantly, Webber ultimately has the pace and thats obvious to see from the Q2 times.
Get up there on the Podium Weeboo!
