Cars of winner Martin Truex Jr., Jimmie Johnson fail postrace inspections at Chicagoland

JOLIET, Ill. -- The race-winning car of Martin Truex Jr. and the 12th-place car of Jimmie Johnson failed postrace measurements following the Sprint Cup race Sunday at Chicagoland Speedway, but the potential penalty for Johnson could be much worse.

NASCAR announced that the cars' rear-alignment measurement failures were at minimal levels, meaning Truex will be able to use his victory Sunday to advance to the quarterfinal round of the Chase for the Sprint Cup.

NASCAR reviews any extenuating circumstances and will announce any penalties this week, likely Wednesday.

Furniture Row Racing crew chief Cole Pearn tweeted that the car failed by 0.01 degrees.

Furniture Row Racing president Joe Garone said in a statement Monday, on Truex's car, "The right rear of our car was well within the tolerance margin, which showed that we were trying to be conservative. However, the left rear wheel alignment was off by approximately ten- thousandths of an inch, which in high probability was due to damage in that area as a result of being hit by the No. 4 car [of Kevin Harvick]."

On Wednesday, NASCAR said the cars that were out of compliance by 0.12 degrees on both sides would result in a driver not being allowed to use the win to advance in the Chase.

"[Failing by that much] will be egregious in nature, it will be deliberate. It won't be an accident," said Scott Miller, the NASCAR Senior Vice President of Competition. "That's what we're trying to guard against."

Johnson faces a potential 10-point penalty, which could drop him from eighth in the standings to a three-way tie for 12th with Austin Dillon and Harvick. The Chase field of 16 gets cut to 12 after two more races, with the winners automatically advancing and the four worst drivers in points eliminated.

Johnson crew chief Chad Knaus also faces a potential $15,000 fine.

Truex also faces a 10-point penalty with Pearn being fined $15,000. If the team fails again for a third violation in six months, it faces the potential to have penalties increased by 50 percent.
