Why I'm so fixated on the front spoiler is that I have several cars that I'm trying to pick from to build a Bonneville coupe for next year. If I run a "stock" class any body mods need to have been produced and sold on that particular model to classify. As you probably know aerodymics are everything there. The same thing with the engine, if it came in the model then great, you can modify the heck out of it.
