But what doesn't make sense is why Chevrolet chose the open rear end with a stabilizer bar between the control arms setup instead of just offering posi? Seems like a lot of extra engineering involved here, and they made sure magazines wrote glowing reviews of how they "solved the traction issues" on Z16 Chevelles, but they obviously didn't.
One theory I had was that they didn't want people drag racing the first 201 they built, possibly to prevent breakage and poor publicity, so they simply stuck them with peg-leggers.
Another theory is that the test cars had the stabilizer bar within the control arm setup, and they actually DID have posi, but did not tell the magazine testers about it.
I can't see how a non-posi rear end could lay down two perfect black marks.
At least that's what "My Cousin Vinny" taught me.
