NASCAR competition officials released a bulletin to Monster Energy Series teams Wednesday, announcing rules changes intended to reduce speeds at superspeedways. The changes include a rear spoiler increased from 8 to 9 inches. Officials will also mandate a 1-inch bolt-on track bar mount to change the height from 11 to 12 inches, raising the rear of the car by one inch. Both changes will be in effect for the season’s remaining races at Daytona International Speedway and Talladega Superspeedway.(NASCAR.com)(3-27-2019)
