Over the last couple of years teams were trying out blown wheel nuts for aero purposes so I was wondering if:
a) it's possible to use the energy(airflow) from the tyre(brake disc) and redirect it or whether their is some FIA technical regulation regarding this ?
b) if teams all have their own individual aero teams with their own ideas and solutions why do the cars all look the same ?
Sorry if I can't be more specific since I don't come from an engineering/aero background
