Hello. I am working on a physics project for a simulation title and have stumbled upon on an interesting challenge.

Below is the example from wind tunnel data of a Dodge Viper GTS sports car.

Wheelbase: 2,44m

Lift front axle: 54kg

Negative lift rear axle: 26kg

Can somebody please explain to me how to:

1. Determine the sum of two opposing forces acting on front and rear axles? I don't think that simply substracting the two values is the correct method here as one must take into account car balance also. For example if you had equal amount of forces acting in opposite directions like 50kg lift at the front, -50kg rear negative lift car would have a large understeer so the sum of forces cannot be 0.

2. Where is the center of those forces relative to the wheelbase?
