On May 17, NASCAR got off to a roaring start with a 38 percent rise in viewership over their last race in March.
But spring and summer in the south often means nasty weather that interferes with racing events.
Such is the case for the second and third races at Darlington Raceway. While the return to racing for the Xfinity Series is in a rain delay; the second race in four days for the NASCAR Cup Series race has a schedule change.
Originally scheduled for an 8pm start, NASCAR has moved the start time for the Toyota 500 to 6pm. Officials made the change due to a forecast of precipitation in the area.
NASCAR uses smooth tires to maximize tire contact with the racing surface; as a result, the cars have no traction when they become slippery and wet. The smooth tires prohibit the drivers from running under wet weather conditions.
After some inversions from the results of the Real Heroes 400 on May 17, Ryan Preece will sit on the pole with Ty Dillon starting alongside on the front row.
The May 20 race will mark the first time since 1984 that NASCAR has run a race on a Wednesday.
