For a real fast breakdown, there are street legal rigs called street and trail, there are non street legal rigs that are broken down by wheelbase and # of cyl.
So like a 106 or longer with a v-8 is a long 8
A 94 inch v-6 is a medium 6
There are short, med. and long 4,6,8
Barrels are just like the horse barrels, obstacle and cross country are both short course races.
Tires dont come into play with the classes at all.
Binder for an example runs in the long 8 class, I run in street and trail...
The long 8 is probably the most competitive class out there right now, but that kinda changes by the year.
There is more, but that is the quick down and dirty!!:awesomework:
