One concern that many have stated is that it seems to be a "no holds barred" style event, which it is far from. Although the restrictions on the vehicles are little, there is one factor that is and that is the driver. There are classes but not by vehicle but by driver experience.

And even with these groups, the track officials can and will move people around who dont quite fit in with the group that they were assigned to. That isn't punitive but just mainly for safety concerns and level driving field for a more enjoyable experience.
