Volusia is a very fun track especially in the 410s. The track will slowly move up throughout the race(s) until it is to the wall. Once the line is to the wall it will begin to move around (if it already hasn't). These sets will help you be quick early on when the line is fairly single file, but be even better once the track begins to widen out and the bottom comes back in. When running the bottom, arc your entry into turn 1 so that you can stay as low as possible down the back straight/D!
