How Does the Floor, Change the Way the Car Handles?

It's all about basically making the car more controllable over a wider operating window. So we see things like the the sculp sculptured sides inside the under floor from the likes of red ball and ferrari at the front end of the the plank area. They've also got these sort of er serrated edges at the rear end. And the reason they're doing that is to try to change the volume of the under floor and the diffuser so that you've got less of a problem when do rid height changes.
