Hi Chris
I must be missing somthing here, whats in Imperial. the position of Center of Gravity is a position of a point that the cars is in Ballance around.as i understand it it's the total values of all of the mass of the car

if where talking imperial Inch than multiply by 25.4mm fine but i was asking about the position from either the ground or from the chassis ?
the Cars CoG will have a physical position on The 3 axis X, Y & Z ( Z being the height)

its position will be differant depending on weight of battery its placement in the chassis, The motor weight even the size of pinion could have an effect as it would move the motor away or closer to the cars center line.

what i was asking is a rough idea , Ive been guessing around the 15 to 20 mm above the bottom of the Chassis , when the car was first designed they must have had an idea of want they required to make the chassis work with the cars geometry

A touring cars will be close to the ground but the off road car will be a lot higher so the position of the RC point will have a lot different effect.
