Perhaps, well it started as the one you could purchase at the dealer, and then when you trade out for all the race parts the only thing left that was stock was probably the key.
I'm sure it's not across the board, but some gear is known to be the same regardless of level. The Arai Corsair V (and now X), for example - Arai says plainly "no one's head is more valuable than anyone else's." They have the balls to put that claim out there and stand behind their product. If this is shown ever to be wrong, imagine the impact that would have on their brand.
I'm only talking about what I know. And what I know is that picking something up off of the shelf and looking at it for 5 seconds tells you NOTHING about how it functions, either in performance or protection.
