KANSAS CITY, Kan. – NASCAR is unveiling its rules package for next season, changes designed to reduce downforce and give drivers more control of the race.
Vice president of competition Scott Miller said the package is similar to one Sprint Cup drivers ran at Michigan, just with a rear spoiler that will be reduced in height.
There will also be a reduction in the restrictor plate, among other design changes, and teams will be allotted fewer tires at some tracks where NASCAR determined there was typically a surplus.
NASCAR also announced parameters for drivers to wear personal biometric devices, such as Fitbits. The information will not be made available in real-time to fans, though that could happen.
