Weight distribution in a kart is an inexact art.

There is no known 'correct' position, because each kart reacts to each track differently and no manufacturer quotes a 'right ' distribution for their kart.

Having said that, we assume that, on a dry track, the kart needs a50:50 lateral distribution and a 45:55 longitudinal distribution (ie, 45 over the front wheels).

You can take your kart to be corner weighed, but in fact using bathroom scales is accurate enough if you calibrate the scales before use.

For testing, it may help to deliberate split the positions of the weights. instead of putting all 10 kg 'on the spot', put 8kg a little to the rear of the 'right' spot and mount 2kg on the front.

This allows you to move the 2kg weight easily until you find the best position for your driver.

One of the reasons you need to test, rather than simply calculate and weigh is because each driver, and cadets especially, will sit in a different position when 'sitting' and when 'driving'. For example, the drivers head weighs 7kg. If he leans sideways in the seat in a corner, that 7kg may move 200 mm sideways. If the driver sits forward as he drives, then the head can move more than 200mm forward and backward.

So the best siting for the lead while driving may be a long way from the sitting in the garage position.
