Wednesday, NASCAR officials announced a slight tweak to the rules package for three upcoming tracks — Pocono Raceway, Darlington Raceway and Homestead-Miami Speedway.
Teams will now be required to use the aero ducts at these three tracks, instead of using brake ducts or block offs. The change was made after NASCAR was able to analyze data from the February race at Atlanta Motor Speedway which showed no issues with brake cooling.
“When we originally looked at which elements of the package to race at each track, we wanted to err on the side of caution at a few tracks where there may be some brake cooling concerns,” said John Probst, NASCAR senior vice president, innovation and racing development. “After reviewing data from Atlanta, and with what we’ve learned over the first 11 races, we believe we can use the ducts without issue. In conversations with the teams, they emphasized the desire to focus on one race package, which will continue to improve the racing.”
