how can i make my vehicle be less affected by gravity in the air?

Hello guys I’m using a chaos physics vehicle. i made my own car and controls to make something arcadish. I reduced the gravity to -5000 and my vehicle mass is 150. And when I go on the ramps obviously my vehicle falls super quickly front faced as it should. But how would I make my vehicle make longer jumps? as to be less effected by gravity while making those long ramp jumps? and how would i follow the road even if its rotated by 90% degrees or less?
thanks in advance! https://www.youtube.com/watch?v=qeJCby0LNv0
