The procedures will be used for Xfinity Series races at Mid-Ohio Sports Car Course, Iowa Speedway and Road America.Â
In the Truck Series, the new procedures will be used at Iowa, World Wide Technology Raceway and Canadian Tire Motorsport Park.
For these races, team rosters will consist of eight crew members and the pit crew â four to service the car, one fueler and one driver assist â must be drawn from those eight crew members.Â During green-flag pit stops, teams will only be allowed to add fuel (unless permission is received from NASCAR to fix damage). Once the field is frozen under yellow (for regular cautions or stage break cautions), teams will not lose their position on the track as long as their pit stop is completed in the designated time period. On oval tracks, teams may add fuel and change two tires per pit stop. On road courses, teams may add fuel or change four tires per pit stop.
The restart lineups following caution periods will consist of cars that did not pit, cars that pit once, cars that pit twice then followed by free pass, wave-around and cars under penalty.
âThe reason we selected the events that we did is that they are standalone events. The standalone events for the Truck and Xfinity that arenât with Cup present challenges for the teams from a logistical end on doing pit stops,â said Eric Peterson, the Xfinity Seriesâ technical manager.Â
âThis is a way to alleviate the burden the teams have when performing pit stops at races that are not companion events to the Cup series. The Truck and Xfinity teams share the same issues at those events.â
Peterson said NASCAR hopes the procedures will help create different tire strategies in these events and level the playing field on pit road, which can see a huge disparity in resources just from the front of the field to mid-pack.
âIf we have had it where they could do whatever they wanted on every pit stop than it would not allow us the opportunity to get different restart scenarios based on what each team elected to do such as a decision regarding two tires or four tires on an oval track,â he said.
Since NASCAR hopes to get away from teams having to make green-flag pit stops in these races, the lengths of stages will be adjusted from what they were in 2019.
Exceeding the time limit on pit road, pitting immediately after an accident and pitting other than the designated lap will result in a penalty of having to restart from the rear of the field.
A two-lap penalty will be assessed to any team that changes tires under green (without NASCAR permission), performs a four-tire pit stop on an oval track or takes four tires and changes fuel on any stop.
Ryan Pemberton, the director of competition at JR Motorsports, said lowering costs was part of the reason teams supported the changes but also because of how the rules should help level the playing field.
place car, one take one of those guys back there that is having a good day, and itâs hard to have a successful day due to their pit crew compared to some of the others.Â
âFrom a crew chief pit point of view, it puts more people in play (in the race). It should broaden the competition of how many guys run in the top-10 on a weekly basis.â
