tires are the big divider.  if you dont have r-tires in a non-street tire
class you have to have something seriously weird with the class to be
competitive.

i never understood the rotating tires business... you replace in pairs
anyway right?  the one thing that can be helpful on stock suspensions with
inadequate camber or roll control is to swap them so the "fresh" edge that
was to the inside of the wheel is now on the outside
