It seems that all the local meets you have three or four different classes. Fast, Faster and Fastest. Call them what you will. Why does FWD get isolated in their own class when we're dialing in a time anyways? A lot of them are holding their own against(and beating) the V8 RWD cars.
The only thing I can figure is that it gives everyone in the crowd a chance to go to the bathroom and visit the concession stand.
