You need to clarify your thinking on this. The concept is about raisaing or lowering your centre of gravity.
Effectively (but crudely), you can think of your kart as a triangle with the 'base' corners being the contact patch of the rear wheels and a point somehere around the driver's navel (belly button) which will be ROUGHLY the centre of gravity.
Cornering forces can be thought of as being applied, sideways, to the CofG. The higher that CofG, the more the kart will try to 'tip over' the base of it's triangle. It would be easy to tip the kart over if you applied sideways force to that CofG if it was 6 feet UP, but damned nigh IMPOSSIBLE if it was 6 inches up!
The higher the CofG, the more force is 'levered' into the 'outside' tyre. Too high and it will simply tip over, too low and the forces on that outer tyre are reduced.
So..... you can choose to apply MORE force into that outer tyre by raising CofG by:-
* Raising the chassis (Moving the axles DOWN the chassis)
* raising the seat more upright
* Moving the weights UP the seat
.....and so on....
You can also get a similar effect by NARROWING the axle width; think about the 'triangle' and you'll see why!
Obviously, each of those 'movements' may well have ADDITIONAL reactions and thus you choose the one that gives as many of the desired reactions as you can get with as few 'negatives' as possible.
However.... having said all that.... why don't you simply TRY moving it and see what your driver reports.... you'll then see if I am talking rubbish or not......
