One thing you can bank on in NASCAR racing is banking, the angle at which an oval track's turns are sloped.
This incline is present at every speedway, but the amount of banking varies from track to track.
Banking is designed to help a car's downforce and velocity through a turn while minimizing lateral slip. The steepest of all tracks where NASCAR races is Talladega Superspeedway, where the main turns are pitched at a tall 33 degrees. But the banking is also relatively flat at certain tracks, such as the 7 degrees at New Hampshire Motor Speedway and the 9-degree turns of Indianapolis Motor Speedway.
A handful of tracks on the NASCAR circuit feature progressive banking, where the higher line through the turns has more banking. This allows cars taking the longer way around the track to carry more momentum than those in the lower (and shorter) grooves, producing an equalizer and more competitive racing.
