First question is how (or if) the CX is any different than a DX, in terms of what we care about for classing/spec'ing in IT.

Second would be either asking for the CX to be listed (if it is substantively different) OR worrying about whether the DX is listed - or listed correctly. Any or all of these things could be initiated by a letter to the club racing office with SPECIFIC requests to do what you want done. This really needs to be accompanied by documentation sufficient for the ITAC to make a decision, including all of the kinds of information you see in the ITCS, explanations of changes during the generation production run, comparisons with similar/related models, etc.
