To the OP, Chris (RedMisted) and Ron are right, AS is very far away from IT, in terms of prep. Aftermarket brakes, aftermarket transmissions, etc., etc. However, as Chris said, they do look like they could be IT cars (probably more than anything else out there). As Steph and Chris (chois) have mentioned, there's a belief that having IT go National will raise costs for some. It may, but then again it may not. I think Chris' highlights of Steph's post show that. To Chris (chois), pay no attention to Travis. He keeps up with his notion that SM and IT are similar, and leaves out how the folks that originally bought into SM were sold a bill of goods vis-a-vis the "$10,000 race car that could run at the front". Granted, costs did go up because SM became popular. Would it have become as popular if it hadn't gone National? No way to know. I suspect that it could have. If SM had not gone National, you'd probably have a situation similar to what you see in ITA along the East coast, people spending big $$$$ to run at the front (and large fields). What's false is to compare a spec class to a somewhat open category like IT, where you have many different options, and therefore get some cars which are better for some tracks. Getting the last bit out of a spec class costs more than it does for a non-spec class. Part's bin blueprinting gets expensive. It's also why you pay 4x - 6x more for a 'pro' SM motor than you do a crate motor from MazdaSpeed. Part of that is that everybody isn't running the same car, so you don't know if the variability is in the car, the prep, or the nut behind the wheel.
