I remember last year they said something like "this car was created to be easy to develop"... and where are those parts? they have a good aero staff, how can it be that they cannot extract more performance from the package?.
Apart from the slow aero development, the mechanical side of the team needs to be reinforced. Maybe the people in charge of this are the same of the old Honda team... I remember that at least the head of vehicle concept is the same (the person in charge of the general weight distribution and car layout), although i don't want to make him the complete responsible of this problem.
