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 downforce, 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. The primary reason for the rule change is to increase competition. In races so far this season, there have been 302 lead changes this season, compared to 396 to this point last year. If the changes prove positive, it is possible the rules package could be used elsewhere. The Sprint Cup Series is idle this weekend for Father’s Day.
