NASCAR said the two violated a rule stating that except as specified, spoilers must be used exactly as supplied from the manufacturer.
Each car is also being sent to the rear for the start of Saturday's race.
Other penalties include a loss of 20 owner points and a $25,000 fine.
Jimmie Johnson and Joey Gase are also starting at the back because of inspection failures.
