Calif. -- A post-qualifying shock measurement Friday sent David Reutimann from the front row to the tail end of the field for Sunday's Pepsi 500 at Auto Club Speedway.
Reutimann's speed of 183.108 mph, second-fastest of the session, was disallowed and his No. 00 Toyota will start 42nd. According to NASCAR spokesman Ramsey Poston, no further penalties will be issued.
"This is a result of [Reutimann's car] exceeding gas-level limits in the rear shocks," Poston said.
After his run, Reutimann was genuinely surprised by his improvement in speed from practice earlier in the day.
"We weren't that good in practice," Reutimann said. "The guys made some really big changes to the car."
Unfortunately, one of those changes might have resulted in the car failing inspection.
"It happened to Juan Montoya [in 2008] at Chicago," Poston said. "It doesn't happen very often."
