This would be a very interesting match. RX8 is lighter and handles a little better than the 350Z but 370Z has much more power and is a bit lighter than the 350Z. When comparing power, 370Z will be the unmatched winner but handling wise, I really can't say anything yet. The new 370Z DOES have better suspension than the 350Z and it's 4" shorter. I guess we just have to wait and see?
