Some bodies are capable of lifting on their suspensions,altering their angle of attack,and coefficient of lift at speed.
Rigid members lock in the static body inclination and prevent any funny business until higher speeds,where regardless of whatever you do,the car in aerodynamically unstable.
I didn't have to address this,as I never went over 105 mph.At 130-mph the truck generated only 22-pounds of rear lift,on a 2150-pound axle load.30-pounds of front downforce.It's gonna be a different case for Gumby79.
One good bit of info from DARKO is,that Spirit is neutral in lift,and it's static weight distribution is almost a perfect 50-50 on the axles.Gumby 79 will have the potential for this in the Diesel 'Coupe" class,as a truck streamliner.
