SME has a 10.0 minimum ET.. you have to have
a legal 5 point minimum roll bar to be legal
in the class... or 11.50 for no roll bar..
but this past year I think all 32 were under
the 11.50 times.. so if you want to even get
into the 32.. yo better have a roll bar... JMO
or just enter into SME and dont worry about where
you finish.. just have fun and see if you can finish
the week.. its not easy
EDIT
You have to have all the stuff legal for 10.0
to be legal for it
