When this was introduced 10+ years ago I hated it. It allowed two sets of rules
for a vehicle to compete in street prepared. I don't know if it's changed since
then (after a 10 year hiatus I am now in a stock class) but I always thought
that there should have been an actual IT road race requirement. (I think I even
wrote a letter to the SCCA.) I never had a problem with actual (read "road
raced") IT race cars competing in the same class. I guess what really peeved
me, was that an "IT" car showed up a divisional (maybe it was in a magazine -
way too long ago to remember correctly) that was specifically built for solo 2
and never had any intention of going road racing.

That would have been Kenn Walker's red ITA/CSP CRX, Brad. And, yes,
it's perfectly legal. The catch-phrase in the rules is that a car can
be prepared to one spec or the other. But you can't mix and mingle.
You can run an IT road race car in its equivalent SP auto-x class as
long as it meets all the IT specs. You can't mix in any of the SP
specs. The rule was designed to give the IT guys somewhere else to
play, since their cars can only run at the Regional level. IT is not
a National class. To my knowledge, however, you can't go the other
way. That is, you can't take a SP car and run it in IT unless it
conforms to all the IT specs.
