Automotive: Aero Balance
 

I searched on here and didn't find any information. I have been working on how to calculate aero balance from OpenFOAM. It should be easy, but I haven't been getting realistic values.

Project:

Baseline car run without aero. I already calculate coefficient of drag and lift. I would like to know the distribution of forces to the front and rear tires (aero balance).

Then change parts like adding rear wing and front splitter. I would like to know how the aero balance changes with these additions from the baseline.

Has anybody done this who could help me out?

Anybody know anything?
