Joe - please read Andy and my posts again. I won't bother everyone with all the quotes this time. I agree with you. The 2.0L type cars that are starting to drop from S to A are the moves that should be made. (Neon, 2000SX, Prelude) etc. Others can follow with requests. (I can think of the 90-95 NA MR2 as an example)
Andy said, this is not what HE meant, and he seems to think that the top half of ITS could serve as the "ITR". I don't buy this because, as you point out, the new cars coming will leave the 325 in the dust.
Bill, I am not proposing to "shut down" ITC. I'm just saying that each year it gets smaller and smaller and may die of natural causes. This is one of the reasons that we need more classes (more granulatrity like you say). In NER (a big freakin region) ITC averaged 4 cars last year. Why should we be scared of adding a new class or two?
So here is one way to impliment:
ITR <--- new spot for for IT cars faster than 325 (a place for T2 cars to go)
ITS <--- maybe add a lb or two to the 325 and loose slower cars to ITA
ITA <--- Fast half of ITA (CRX, Miata, 240, Integra) + silly slow ITS cars (2000NX, Neon, Prelude, and others)
ITB <---- about 75% of the current classified ITA cars (RX7 and slower)
ITC <---- Move ALL ITB cars here
ITD <---- Move ALL ITC cars here
So there you have it, 6 classes where there were only 4. In reality, ITR will be tiny for a while, and ITD will be tiny as ITC is now, and only get smaller.
