Keep in mind there are some things GM has to have because it has them on other vehicles. You can remove a lot of things, but simply removing everything is not practicle.
Yes, you could take even more stuff out/off. That isn't the issue.
Take the window regulator for example. To engineer, test/validate a manual crank window would easy to do. And yes you could spend the additional money to tool up that crank window. And then if you divide the cost of the engineering, testing and tooling by whatever number of Z/28s you expect to sell you will find that you just added another $XX to the cost of the car AND you would have a door that wouldn't close because the Camaro was designed with indexing glass so that at high speeds (say those seen at a track day) the window will stay sealed. So now GM would have to engineer an entirely new door seal just for the Z/28 to have manual windows. And that is wayyyyy more than $XX. And what would you have saved for that? The weight of two small power window motors that weigh no more than a few pounds. And you would be adding back in two cranks.
Just know there is much more to this "how much can you take out" game than meets the eye. It's not as easy as you all think.
Not to mention crank window control would weigh more than the electrics. Pointless exercise. And for those complain gong about the radio. I haven't tuned mine on since I tested it at the dealership 3 years ago. Engine sounds too sweet. I suspect the Z/28 will be as pleasant.
