NASCAR’s executive vice president and chief racing development officer Steve O’Donnell announced Tuesday that Sprint Cup teams will have a new aerodynamic rules package when they head to Kentucky Speedway for next month’s Quaker State 400. In an effort to reduce down-force, the new rules include a smaller rear spoiler and a new front splitter. In addition to the new aero package, the tires supplied by Goodyear will provide the drivers with more grip. The teams will be given a full day to test with the new rules on Wednesday, July 8, prior to the race weekend.
For now, the rules change is only for the race at Kentucky on July 11, but O’Donnell said that the changes could also come to other tracks this season if the changes prove successful. “We want to see more lead changes on the racetrack,” O’Donnell said. “We’ll evaluate that and a number of different factors coming out of Kentucky, see what we can learn and implement down the road.” There have been 302 lead changes this season, compared to 396 to this point last year and the hope with this package is more competition and increased lead changes. O’Donnell maintained that NASCAR is committed to putting the best racing on the track and that the work would not stop with this announcement.
