There are cars that weren't meant to be airborne, this one is heavy, you can't get enough weight on the rear compared to the front ( F/R weight distribution ), and you won't have enough power for the weight of the car. There are easier cars to do this kind of thing with, the easiest one I found was the Delta Wing, it looks like an airplane and you don't have to do much to it to get it to lift off. The Subaru 360 works well (kind of amazing for such a low powered car, this is the link to itFly Me To The Moon Tuning Garage ), there' s also the Veyron done by @Dagger311 (link) https://www.gtplanet.net/forum/threads/haus-of-flying-daggers.301978/page-2#post-9372451, hope this helps you, have fun with with your venture,
