NASCAR will commence the All-Star Race a week after the Kansas Speedway race this Sunday. The sanctioning body has made changes to some areas of the exhibition race, including the length of the heat races and the addition of a caution.Since the 2023 season, NASCAR has been hosting the All-Star Race at North Wilkesboro Speedway. The non-points-paying event, which was inaugurated in 1985, was previously held at tracks like Texas Motor Speedway and Charlotte Motor Speedway.This year, fans can expect a few adjustments that are seemingly meant to enhance the on-track action. NASCAR insider Kelly Crandall took to X (formerly Twitter) to share some of the changes for next week's contest."From earlier this week: NASCAR has adjusted the length of the All-Star heat races and added a caution," Crandall wrote.The report stated that the two heat races will host 75 laps each, translating to a 15-lap increase. In the world of racing, a heat race is a preliminary event that determines the starting lineup in the main stage.The other change is the so-called Promoter’s Caution. The new rule ensures caution will be thrown in the race, allowing the pack to get back together for side-by-side racing action. However, it must be used before lap 220. If the yellow flag comes out due to an actual on-track incident, the Promoter’s Caution will be disregarded.NASCAR has been hosting the All-Star Race at North Wilkesboro Speedway since 2023 - Source: ImagnThe All-Star Race weekend will kick off on Friday (May 16) with the qualifying session and the Pit Crew Challenge.
