...a smaller front opening? This was a statement by NASCAR about the penalties for Bowyer

"It’s not fun for anybody, but we’re here to make sure all our competitors are on the same level playing field.”

With that being said, when Toyota designed their engine for the cup series a few years back, Toyota was not held to the same specifications as Dodge, Chevy, and Toyota. Toyota was allowed to have an engine with wider cylinder bore spacing, which allowed for a cooler running engine. With a cooler running engine came more horsepower, and also Toyota was allowed to submit a request for a front design with smaller openings for the radiator, which in turn gave them more downforce on the front of their cars, which equaled to a better handling car [a car which would turn better (the secret to Kyle Busch's success)].

If Toyota was allowed to have 1) and aerodynamic advantage and 2) a horsepower advantage for several years... then how is this statement that quote "we’re here to make sure all our competitors are on the same level playing field” considered true in the event of Clint Bowyer's car being found less than a 1/16th off of specs [according to NASCAR]?

If NASCAR doesn't even know how that fraction of a 1/16th of an inch would even give someone an advantage, then why even penalize them, much less with a stiff penalty of a 150 points reduction?

It's very clear that Toyota was allowed to have an aerodynamic advantage as well as a horsepower advantage by NASCAR for several years. So why the big concern over something that NASCAR isn't even sure would have given Clint Bowyer an advantage?
If no rules were broken, then why did NASCAR refuse to let Chevrolet submit their new engine in the Busch series with the same cylinder bore spacing? NASCAR basically forced Chevy to use older technology engines, even when they were ready with the same technology as Toyota. Then Ford and Dodge were not caught up yet on developing their new engines for sometime later. Acually the middle of this year.

So if the rules say you have a certain cylinder bore spacing and a manufacturer doesn't follow the same specifications then you are saying they didn't break the rules? It sounds to me like NASCAR allowed the teams to break the rules.

If so, how can you trust that NASCAR's intentions are to "make sure the competion is level" after allowing someone to blatantly "break the rules"?
