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....
They did coast down tests and airport runway tests with spring compression measurements and a host of other processes. Lots of techo work involved, plenty of tech dudes from the category and teams at the time, measurements of various drag inducing items - there was a lot to it.
