That’s stunning speed for a stock car. I know the temps were optimum too, but that’s impressive.
Shallow banking and serious speed at Michigan prove that restrictor plates are unnecessary in my opinion. The drivers will slow for the turns.
Its been routine for at least a decade for them to enter turn 1 at 200+mph. When I worked security there I used to get stationed right at the entrance to turn one where they were right out by the wall and wound out and going full tilt. That’s astounding speed for that much car and it rocks you in the wind.
