Vehicle jumping

hey pal sorry for late, i created it with a combine of GetUpVector and GetForwardVector and 25 vectors of the Z axis. and it worked better but there was spinning when the car was steering around and i’ve been pressing space bar. so i changed center of mass and that got harder (the vehicle was dancing great) so i changed many other things and it didnt work. then i went to blender to see the model and measure dimensions to calculate the center of mass and finally it really worked nice on Z axis -40 , thank you so much for the help, cheers.
