As you've seen, in the software are already entered many chassis, kart, engines, and tires, anyway, if you need, is really easy to enter independently the necessary data to the calculation.
	Lengths, diameters, angles are easily measurable, regarding elasticity is possible to refer at the data of similar chassis in the list, instead for torsion you can use the utility on our web-site, or for the Experience version, directly entered in the software one.
	For the data regarding kart, it's necessary to check total weight, front weight, and gravity height. To calculate the gravity height in all the versions of the software there is an utility that allows to make it with a simple experimental test.
For the data regarding engine, these are importants only for engine with gearbox, instead for the inertia you can refer to the data of similar engine in the list.
For the tires you can find practically all the data in the homologation fiche , in addition to these, the other data are already entered internally in the software, and regarding the ply stiffness you can contact NT-Project to have the informations in function of the canvas angle and of the manufacter.
