Interesting question. Would it even fit? Also you would lose the diff cooler and the ZL1 chunk is iron Vs aluminum for the hammerhead. I wonder if it is weaker or stronger? I would assume it would be lighter but how much? I have yet to hear about someone breaking a ZL1 rear even with a ton more power and slicks. A better question would be is anyone developing additional gear sets for the ZL1 rear.
