How can one actually measure such downforce? I have a car ( not a V8 supercar ) which has a front spoiler and a rear wing. How can I measure how much downforce ( hopefully ) it creates now so I have a baseline to understand if any future changes increase or decrease that downforce?

I imagine the pros put the car on corner scales in a wind tunnel and blast air over the car at 200kph, then read the scales? I have the scales, but not a 200kph wind tunnel....
