I have apparently had to much time on my hands as of late and been thinking allot about the weight of the Z. Has anyone heard of an aluminum chassis for the Z? The current one is fine, with little flex but the weight of it seems to be what makes the z so **** heavy. If I remember the chassis is the same one used for the suv nissan makes. It stands to reason that if the chassis could be made out of aluminum it would do very wonderful things for the car. I don't know if this is a feasible thing to do or not but I would love to see some discussion around the subject.
