From my CRG manual....

Think of the relation of the rear hubs to the axle and chassis as you would your hand to a pry-bar and
an object at the other end of the bar. If you hold the bar at the farthest end of the bar or hold it with less
of your hand, you will have less leverage. Rear hubs on the axle work in much the same way.
Longer hubs tend to provide more rear grip because the inside rear wheel will spend more time on the
track surface. So if the kart oversteers as it exits a corner, a longer hub may be desirable.
Short hubs are used when the kart understeers at the exit of the corner. If the driver runs out of track
surface as he/she exits the corner the kart has a “push” on exit. While it’s not the only possible
change, switching to shorter hubs will reduce grip at the rear and may be desirable in a situation like
this. The shorter hubs have a lower “frequency” and will allow the inside rear tire to stay off the track
surface longer, and the kart will have less grip on corner exit.
Overall choice of hub length should ultimately be based on how flat the tire is wearing. If the kart is
running little caster, a soft axle and generally feels good, but the rear tires are “coning” (the inside of the
tire is wearing faster than the flat or outside), decrease the rear width. If the problem persists, increase
the hub length or turn the bearing carriers facing out to support the axle end more.
