SM is probably club racings biggest success story in the past few years. It is a great class. It is not the same class as when it was started, but that is not a bad thing. [/b]
You are making part of the point for IT going national, or doing away with the regional/national seperation.
Few could debate that SM is a success story. But why is it a success story.
Is it a popular car? Yep but it is a "spec" series and only one car. That would take some people out that just want to run something different, thats why there are IT Hondas, VW's Triumphs and Opels... difference, take a car you like for one reason or another...and some people are a little crazy
As far as getting a top 10 IT car on the track it is pretty cheap, and would stay cheap when looked at line by line with a prod, touring, GT, or SS car. If you look at what else you have to run to get into SCCA racing and have a "sedan" type car the price is crazy, I would think that any other "fender" class is going to be more then SM, and IT would be the most cost friendly of them all, and would stay that way, depending on car choice.
The SM cars are pretty easy to take care of, they do not require the work of a prod or GT car. The only thing that I think would require less time wrenching on is a SS car, as far as fender cars go. A touring car is Big $$ and a SS car is pretty darn spendy also.
IT has cost, variaty, relitive ease of car prep, stable rule set, and a vast driver base to draw from, that is why it is so popular.
I think if IT went national the entrys for ITS, ITR, ITA would be neck and neck with SM for car counts, and ITB, ITC would be above GTL, F500, and a few others, I would bet. And this is the reason why the powers at be do not want IT to get national status. Talk about upsetting the apple cart! That is one reason I think it will not happen, but I am a glass half empty kind of guy.
Sure you can buy a Bimmer world or Millege engine but with all the drive line layouts, susp. mods, tires, swaybars, on and on that is different per car.....that a couple of horse power is not as critical as in a spec series. An ITA MR2 is worlds different then an ITA Miata. (not the best example) But the major differences in the IT class is one of its great streangths and one of the things that will make 2HP not that big of a deal, I won a rain race a while back in the MR2, why it could put power down better then any other car on the track, thats the only reason I won and I know it, at the time I was not in a better car or a better driver then the cars and drivers I beat.
The key here is difference, and a small amout of individual car modifications.
If having more cars come into your class, more and better drivers, better prepped cars as a down side then yes I agree, all these things will happen if IT goes national...and your static, stable, always top 10 finishing spot will be harder to keep if you do not up your game. We are the "entry" class and we can stay the entry class, the cost to join is always going to be one of the best buys in SCCA.
That 1987 ITB Toyota Corolla FX-16 in the classifides will still be a mega deal, and I doubt the price would go up.
