After testing several alternatives and receiving input from drivers and teams, NASCAR is set to make adjustments to the rules package for the majority of road course and short track events in 2023.
The sanctioning body announced the impending changes on Tuesday, which will include a two-inch spoiler and the removal of three three diffuser strakes and engine panel strakes, which will lead to a 30-percent reduction in downforce.
"We saw incredible racing throughout the 2022 season, especially at the intermediate racetracks," said John Probst, NASCAR Senior Vice President and Chief Racing Development officer. "Our goal is to have the best racing possible everywhere we race, so during the off-season, we went to work on adjustments to strengthen the racing on short tracks and road courses. Adjustments will be made to the car that will create a significant reduction in downforce, and based on driver feedback and what we saw from the January test in Phoenix, we're excited to see the results of these efforts."
These changes will initially face on-track action at Phoenix Raceway in two weeks, for the first of the facility's two NASCAR Cup Series dates from March 10 to 12.
As a result of these changes, NASCAR has made Phoenix Raceway an 'extended practice' weekend, with drivers and teams getting a 50-minute practice session on Friday, from 4:35 PM to 5:25 PM local time.
The following ten tracks are scheduled to utilize NASCAR's new rules package: Charlotte ROVAL, Chicago Street Course, COTA, Indy's Road Course, Martinsville, New Hampshire, North Wilkesboro, Phoenix, Richmond, Sonoma, and Watkins Glen.
