there are some shift kits that make better shifts and there not bad, but then theres the shift kits that are out and out hard shifting, and in turn neck snappers. If the clutches are snapping closed fast, I would assume that would be kind of hard on there physical stability, but not on the friction material, where as if there slipping a little, the friction material would wear out faster but there physical strength would stay ok.
