Maybe not but the very fact they came to the ring to set a record is proof enough that they were wanting the world to know how good their cars were.
Nissan has had a long history at the ring and using it as a PR exercise so we knew that they of all people would be shouting from the roof tops about the ring time they achieved, but I personally think GM have been pretty active as well lately with the CTS-V and ZR1.
You can't excuse the other just because they don't capitalise on it as well as Nissan do, if you class tweaking the suspension as cheating then this will probably include quite a few exceptional times.
