Regarding DC and the wheel, I thought DC asked permission from Mclaren to take his wheel and allow RedBull to have their way with it.
As for the car, certainly Renault, Ferrari and even Mercedes looked closer to the Mclaren than the previous few races, whilst RedBull seem to be getting further away, the chasing pack is turning into a great battle. Development will be key. We all know how great Renault proved in that area last year. I would like to think Mclaren have what it takes to overhaul the gap to RedBull whilst increasing the gap to the following teams.
