`What is the point of a flexy seat if you then put a couple of stays on to it?`
Perhaps there is flex between the bearing hanger on one side of the kart and the fixed seat stay (the bit your seat normally bolts to) on the same side of the kart. A seat stay would certainly stop some of this flex.
Perhaps, as PaulM alluded to, the seat flexes to a limit and becomes stiffer than the stay. At this point, the seat stays would certainly stop any further flex relative to the two fixed stays?
Perhaps the seat stays simply stiffen the seat. A stiffer seat certainly feels different to the driver, regardless of whether it has any performance impact on the kart.
Not that this is scientific evidence of any sort, but the fact that mechanics past and present that win at the highest levels use them as a setup option certainly suggests they do something.
