Yes, that was quite helpful. Although it appears you're not totally correct. Some cars are in different classes if they're in Stock or Street Prepared, my car being one of them. Stock it's GS, Street Prepared it's DSP.

Took me a bit of searching but I finally found a site that has the base letter (I guess that's what it's called, I just made that term up) of my car.

But that's only good if you're in Stock or Street Prepared. What about the other categories? I have a feeling my car would be in one of the other ones. That's what their website says: http://www.vmsc.org/novice_class.html
