Softer seat will allow the kart to flex better and give you better lift.
Stiffer seat will stiffen the kart and reduce lift.
Too stiff and you’ll feel the kart get “on top” of the rubber and never dig in because it can’t lift and generate sidebite. Too soft and the kart will flop around like a wet noodle.
