Yes it is I Matt...
cool, I am working on a New ZR1, box stock with some carbon fiber decals, do you remember can you enter a theme car in a regular category (box stock) and still have it be up for a best theme award? I forget how things work.
I think the theme is separate. If you have a car in the theme category it's not eligible for the typical "class" category. I think it's because of the time needed to go back and forth from the theme to the classes to judge the entries. Since there could theoretically could be 1 car from each class in the theme.
