Spec means, equal not different.
I understand and agree with the reasoning behind encouraging low cost for a spec class. However, my interpretation of spec leans more towards equivalent rather than equal (identical).
For example, with the question of wheels, if it is decided we can run any wheels, then I think the rule should specify one piece wheels with a 15lb min weight, no modifications vs requiring a specific manufacturer. That means you can run cookies, phone dials, any aftermarket and they'd all be equivalent. No performance advantage for those that want to spend more for wheels that either look nicer or give them a greater sense of comfort with regards to safety.
Another example where it's pretty much open in the current rules is race seats. In our rules I believe it says the seat must comply with the NASA CCR, that's it. So I can get a basic Kirkey seat for about $500 or I can get a Recaro carbon containment seat for about $7,500. Yes, it costs way more than the car but maybe someone feels safer in it, who knows. My point being that they are equivalent and if someone has one of those $$$ seats it's not going to make them go any faster or win more races. So it's not necessary that they be identical down to the manufacturer.
