My wife has a 1985 Peugeot 505 and I had a 1985 Peugeot 505. Same car, same year, same tires. Mine sat about an inch lower and had slightly stiffer shocks and there was a big difference in how the cars handeled in crosswinds, among other things.
And then there was the time I was following her home, she was driving my car and I was driving a VW bug. I was getting blown out of my lane and she didn't feel a thing.
My gage of wind stability is how the car feels when a 18 wheeler comes by on a two lane road. Now thats scarry on a motorcycle
