CHARLOTTE, N.C. -- Greg Biffle's team is unlikely to be penalized for the No. 16 Ford Fusion's low roof height at Bristol Motor Speedway, NASCAR officials said.
Robin Pemberton, NASCAR's vice president for competition, said the car was too low after the race on Sunday.
Pemberton added on Sunday inspectors wanted to go over the car completely at the R&D Center in Concord, N.C., before a ruling was made.
While no ruling has been made, NASCAR officials are leaning towards leniency, because the infraction was not deemed blatant.
Biffle's car, as well as the No. 5 of winner Kyle Busch, were taken to Concord as part of what will be a routine process as NASCAR implements the Car of Tomorrow this season.
Busch has already gotten his car back. That was good news to crew chief Alan Gustafson, who plans to use the car as a backup at Martinsville this week.
However, not all went smoothly for Busch at Bristol. NASCAR fined Busch's Busch Series crew chief Mike Bumgarner $2,000 for violations for a component that did not conform to NASCAR rules during opening-day inspection.
