Watching the video I was wondering why the old Nascar car was so hopeless going round corners, then I remembered that Nascar races are on steeply banked tracks so they don't need to be built to go round corners on flat tracks.
I was going to say that Nascars have the suspension and tyre pressures adjusted, usually on the rears only, even during pitstops to suit race conditions and the fact that they are racing anti clock around the oval, so that the set up will have a bias from the right side to left side of car.
But then why wouldn't you set the car up for a conventional circuit that has left and right hand bends, obviously I'd say it's down to weight of the cars, you can see in the video how the Cortina is quicker around the curves being lighter and with a more taught set up but slower on the straights due to lack of horse power.
It made for a fairly evenly match race between those two, as the driver says, he only just beat the big bruiser over the line by a car length, it storms past him just as he crosses the line.
