Center of gravity
 
I'm looking for the Cobras approximate center of gravity height for some suspension calculations. Doesn't matter if it's from an original car or a kit.

Any ideas?

Purely an educated guess, but I'd place it at about 12 inches from the ground, plus one, minus two.

I would be surprised if it's above the hub line of most examples.

CG height seems to be 16.5" for the FFR spec racer, just found it on the internet. I also had expected it to be a bit lower like in the 12-14" range.

I also found an interesting way of measuring it: http://home.earthlink.net/~whshope/id31.html

This is another tabular approach:

two rules of thumb on cg----camshaft centerline, belly button height

Cobras have so little weight above the engine centerline that it seems 16 inches is much too high. But as I said, mine is only an eddicated guess. Maybe fat driver heads pull the CG up? :D

Looking at all the components in my 3D layout, I'd estimate our chassis with suspension, plus the engine and trans is about 14.5"-15". Add the body (~24") and other miscellaneous and I wouldn't be surprised to end up with over 16".

I will get a suitable scale and give the tilting method a try.
