greg,

I have a small issue with the ITCS into ST rules: IT cars under 2.0L are not necessarily defacto legal in STL.

as written, a car conforming to the ITCS may compete in STU and thus may be in violation of STU specific rules so long as it is legal to the ITCS.

but the same is not true foe STL. the gotcha I keep going back to is the fire system, which is not required in IT but IS required in ST, just as it is in Prod and GT. Unless the rules change to allow IT cars under 2.0L conforming to the ITCS rules into STL, only those with such upgrades may legally compete there*. I don't think I'd make a big fuss about it myself, it makes more sense for the smaller cars to be in STL, and STL needs numbers, but that is how the rules read, currently.

*the exceptions being cars like the Integra type R, S2000, and Celica GTS or other Toyota with a 2zz-GE where the factory engine is specifically disallowed or violates the rules without modification.
