Those are the published weights for both cars with passengers from what I remember

"Balance" is a lot more than just weight distribution of the engine. I think that is what people are referring to and are not being clear about it. Example the COG of the cars, the twins are lower to the ground and that changes the driving dynamic. The twins are just a better balanced car in terms of handling, feedback, driving position, the car is much lighter, etc.

That is what I refer to when I say the FRZ is a better balanced car than the 370z. Just watch the Chris Harris video again, he explains it better than I do.

Balance also includes steering ratio, power delivery, and amt of power for the chassis setup. The total balance of all the parts are very good, for example its not like a muscle car where you have infinite amounts of power but when you come to a corner you gotta slow right down then get on it again. Love watching ppl drive there muscle cars around the corners in a city lol, total opposite of the twins.
