They have a really in-depth scoring system, which has made it one of the more popular fantasy sports on their site. SpeedTwitch - Get Your Speed On! [4], Handling in corners is affected by balance changes caused by the draft: the leading car has normal front downforce but less rear downforce. He said the drag created by the boxy truck designs, as well as less horsepower than Cup Series vehicles, put drafting at the top of the strategy list. Drafting isn't limited to auto racing, though it is most effective at higher speeds where there's more energy from a moving object displacing air therefore creating a slipstream behind it.
