NASCAR determined after the race that a magnetic spacer was attached under the gas pedal of both cars for the intent of compromising the chassis dynamometer test.

The infraction came several weeks after NASCAR ordered that all Toyotas use a smaller spacer that would knock about 15 horsepower from their engines.

Toyota had won 14 of 21 races, all but one in a Camry fielded by JGR, before the mandate.

This is why I don't consider NASCAR racing. When someone wins a bunch, the ruling body changes the rules so everyone else can catch up. What reward is there for doing your job better than the other guy?

If winning a race is down to timing your fuel and tire changes better than the other guy... why have the race? just park the cars and run it all through computers.
