Lets start with the basics. (first of many)

Hi nis, i dont find any question on your part so i dont know what do u really want to discuss  Cheesy

Anyway i dont know why COG height shows kg´s value.

One of the best ways to calculate the COG height is the following one.

  [50% of car heigh - ( Front RC height + Rear RC height + Ride Height / 3)]

This wont be exactly becoz every car have diferent Y axle weight distribution. but is fairly accurated.

Example: (Lancia Delta Integrale S2 16v T - 16x50 )
Height = 1365mm
Ride Height = 204mm
F-Roll center = 242mm
R-Roll center = 256mm

[ 682 - ( 204 + 242 + 256)] = 448mm
                         3
As u can see is around the 35% of car height wich is the "Standar way to find the COG", but i learnt this one and found it more accurated.
