Maybe for those who have bought their 370Z already, we can get a weight on spare tire and jack/tools. Thats one of the easiest places to drop weight.
Also, some one should try to weigh the stock wheels and tires, as this is another good place to save weight. My estimates would be 24-25 lb front wheels and 27-28 lb rear wheel but I'm just guessing.
