NASCAR competition officials issied a bulletin to Monster Energy Cup Series teams on Wednesday (March 27) about rule changes at superspeedways.
These changes consist of the rear spoiler increasing from eight to nine inches, as well as a one-inch track bar mount bolted on the car, raising the height of the rear of the car by one inch. These alterations should lower speeds of the cars at Daytona and Talladega for the remainder of this year.
A test session conducted by NASCAR officials on Feb. 18-19 using the tapered spacer concluded with higher speeds than they preferred, according to a NASCAR spokesperson. The rule changes should keep speeds in a safe range. The spokesperson also mentioned that officials “do not anticipate any changes to the style of racing at Daytona and Talladega.”
The teams and drivers who participated in the two-day test were:
No. 8 Richard Childress Racing Chevrolet for driver Daniel Hemric
No. 42 Chip Ganassi Racing Chevrolet for driver Kyle Larson
No. 88 Hendrick Motorsports Chevrolet for driver Alex Bowman
The Daytona 500 marked the final restrictor plate race for the foreseeable future. The next Superspeedway race will be held at Talladega Superspeedway April 28.
