BROOKLYN, Mich. — The “little wrinkle” was foremost in the mind of Chevrolet Sprint Cup program manager Alba Colon even as Sprint Cup teams completed final preparations Saturday for the Quicken Loans 400 at Michigan International Speedway.

NASCAR vice president and chief racing development officer Steve O’Donnell had telegraphed last week during an interview in England that the series is considering implementing new aerodynamic packages, he said to “kind of cater it to certain tracks,” depending on their size and level of downforce required. On Monday, NASCAR conducted a teleconference to inform teams of its intentions to take measures to stoke competition, proposing ideas without yet offering final decisions.

The series has acted unilaterally, but found a mostly accommodating garage, partly because the series wields great power, partly because many stakeholders consider the “show” stagnant. A prevailing question now is whether there is sufficient time in the middle of a season to perfect the next adjustment.

“There has to be,” Colon told USA TODAY Sports. “If you ask an engineer, there is never enough data. That is our philosophy. But that’s the beauty. You get a problem thrown at you and you have to make it work, whatever it takes. It’s just part of the game, you know?”

Richard Petty Motorsports director of operations Sammy Johns said he has been pleased with NASCAR’s level of interaction and agreed that some sort of change must be made.

“We need to have more passing. We need to have more lead changes,” he told USA TODAY Sports. “I think that’s what fans want to see, racing close together and passing each other for the lead, not one person leading every lap and checking out. I think that’s when they get bored with the race.”

NASCAR could in essence test a new aerodynamics package that would decrease downforce at the July 11 race at Kentucky Speedway, the type of 1.5-mile track that comprises much of the schedule. That package could be deployed for the remainder of the season or be shelved totally or until 2016. Colon said Chevrolet has not been informed of a final decision.
