Yes, I think the Air will need RWS that will help with a lot of the push they found and somewhat shrinking the feeling of the car. Otherwise, I would not go down the route of big aero, ripping back seats out etc. Maybe a carbon fiber roof. And I believe the Gravity's charging and cooling system can handle better thermals. On big tracks like VIR and Edmunds the Sapphire won, on tight tracks the Porsche will.
