i plan on getting new swaybars myself. I have heard good things, but i am willing to bet that the night and day difference has to do with the replacement of the stabilizer bar endlinks, which tend to wear out.
i don't know if the ST swaybars are authentic on ebay, but the ones on enjuku's site are silver and the ones on ebay are green and i don't see any endlinks in the picture where as enuku's comes with them.

it looks like if your going to go ST, your probably just as good off to keep your stock front swaybar and replace the endlinks and bushings and just get the ST rear swaybar.
Largus is overkill and they cost 2 much.
