Grattan.....this explains why the pavement was so rough in the mid 80's. It never recovered from that Charger grinding it's wheel rims into the asphalt.
It would have to have some traction to create inertial body roll. What appeared to be body roll in the video, was the earth tipping off it's axis from the weight of the car.
That’s when the world starting going to shit. When it went from Speedvison to Speed. Sad times. Sad times.
