different tracks vary, and sometimes are stricter than guideline but....
11.49 and quicker needs a cage
'vert is slower...not sure , used to be 13.99 and quicker , but they changed everything this year. i'd guess it is 13.49 now
slicks (not cheaters) need long wheel studs + open lugs.
slicks needs ds loop
slicks need scattershield at 12.49 and faster
some of these may be wrong , but what my track says
can't think of any other important ones
