Wow long thread...
I think Button likes a glued- rear. While lewis prefers the slight oversteer. Jenson's championship came from the double diffuser which planted those rear wheels, and last yr's diffuser had a similar thing going.
This yr, not only there is less rear bias in the dforce but it seems the car keeps constantly changing.... So Jenson is pretty picky and is swalloing air.
His contract... Dont think webber's contract are solely down to age. Dont think Mclaren has the same views on older drivers as Red Bull.
Lewis is probably not commiting to any team, as he's prob looking for the better deal. So they secured Button and deal with the other contract when the time comes.
Hulkenberg and Button dont sound so bad for Mclaren, when Lewis goes to Red Bull

Came out fighting indeed.
