Made me wonder though, if they stuck that 305 rear on a wider rim on the ZL1, therefore stretching the tire and reducing some of the overall grip, would that help the ZL1 become more neutral and easier to rotate in the corners? Or would they also have to fatten up the fronts like they did on the Z/28 to get that effect?

I don't think it's quite as simple as a wider wheel reducing grip. On one hand, the tire should gain a little vertical stiffness assuming you maintain the same inflation pressure. which will tend to reduce mechanical grip slightly. But on the other, there will be less tread distortion, which improves the situation . . . at least as long as you can still get (or keep) the tread similarly flat on the pavement. I'm quite sure you'd have to revisit the front wheel size, since reducing the rear slip angles without affecting the front slip angles is by definition additional understeer.
