I see, a carried over chassis being a chassis focused on the season before and the season 2 chassis being brand spanking new. Good approach that, Force India style!
Tom, it's 1 chassis that got totally discarded, 2 updated chassis based on last season's cars. 1 totally brand new chassis, and another update of the better of the 2 carried over chassis from last season
I will decide on which chassis I carry on with once I know the new chassis potential. If it's less then my current carried chassis then I will simple start a new chassis again and repeat until I get a better chassis.
I just made one and told my designer to make sure it is good and because i have a good relationship with my staff he did and it has excellent potential! -so there....nah nah.
