I've been waiting for a spec sheet like this for a while! Thank you.
Biggest things I see are that the manual transmission has zero changes from the 370z to the new Z, although I don't see anything about what clutch it will be using. I assume the Exedy. Also, the final drive is slightly changed.
The weight from the 370z Sport Manual to the new Z Performance manual shows that we have gained 339 lbs, but with the new torque numbers hanging on from 1,600-5,600rpm we shouldn't notice that the slightest.
Now we just have to wait on an official 0-60mph time.
Sidenote: My elbow and wrist took a beating from a motorcycle accident I had last year. I am currently unable to drive a manual, but I am having surgery next week and they say it should get me within 90% of normal movement. I am still extremely nervous though. I don't know if I'll even want the car if I have to buy an automatic...
