NASCAR is trying to eliminate technical advantage so that the competition is entirely about which driver and crew is best. I don't see anything wrong with that.
And if that were really the case then you wouldn't see the big teams like Hendrick and Penske dominating. Heck, even Chip Ganassi has problems competing in NASCAR and he's hardly a small player.
Not that I'm necessarily anti the NASCAR approach (though I do think the organisation itself can be somewhat capricious), but it's certainly not a form of motor sport without team-based technical advantage.
I don't think there's anything wrong with that. It's just a different philosophy. Personally I like the ability for engineers to innovate in F1 more, but of course that varies from person to person.
