NASCAR using restrictor plates in All-Star race at Charlotte
Wed., April 11, 2018
NASCAR will test a different aerodynamic package in next month’s All-Star race in which the cars will have restrictor plates at Charlotte Motor Speedway. The plates are used to choke horsepower and slow speeds, and they are used at Daytona and Talladega, the two biggest and fastest tracks on the schedule. The aero package that will be used in the May 19 All-Star race is the same that NASCAR tried in the Xfinity Series race at Indianapolis Motor Speedway last year.
