NASCAR allowed racing without restrictor plates at the Talladega Superspeedway in 2019. The plates had been required since a frightening crash took place in 1987.

In April 2019, at the Geico 500 event at Talladega Superspeedway, NASCAR did not use engine restrictor plates for the first time in thirty-two years. Instead, the cars used larger spoilers and splitters to increase aerodynamic downforce to reduce speeds. The overall effect reduces horsepower and increases drag.
