NASCAR updates rules package at Pocono, Darlington, Miami

NASCAR issued a memo today announcing the rules change

Pocono Raceway, Darlington Raceway and the championship race at Homestead-Miami Speedway will see an adjustment in the rule book. The rules adjustment is specifically for the Monster Energy NASCAR Cup Series field.

Previously, it was announced that those tracks would be run without aero ducts. That is no longer the case.

Atlanta Motor Speedway, the second race of the season, was run without the aero ducts. Following evaluation of the data, NASCAR has decided they don’t want to see that package again.

Thus the above races will be run with an 8″ spoiler, standard radiator pan, larger front splitter and now aero ducts. This is in addition to the tapered spacer installed on the engine with reduces horsepower and slows the cars down.

The cars will have more downforce and the less horsepower as the previous season.

“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,” 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.”

Green flag passes are up significantly for the 2019 racing season. Specifically, this is true for the 1.5-mile tracks.

This change is completely unrelated to a backlash from select driver following the race at Dover International Speedway. The race at Dover was run with full horsepower, a different package than the one discussed here.
