additional IT cars that ARE legal in ST even though they aren't compliant to the ST rules (I am not arguing against this, just pointing out that the people readng the cage rules are missing other opportunities to be wrong):

1)ANY ITR car running the maximum allowed wheel rim width for ITR (8.5") in STU or L.

2)Integra type R or S2000 (2.0L) built to ITR rules in STL

3) any 2ZZ-GE powered car (ITR Celica GTS, ITS Corolla XRS) in STL (too much valve lift)

4) Many cars which are underweight by the ST class rules when running at ITCS prescribed weight, such as the Mazda Protege ES 2.0L (ITA), Lexus IS300 (ITR), Nissan 300ZX (ITR or ITS), MAzda miata (ITS), etc...
