the main features of the preload spring(s) is that it holds the clutches under some load and therefore the load changes are smoother, especially if a setup without this spring has worn out a little. then there is too much clearance inside and load changes will let the lsd react pretty extreme from loose to fully locked.
so if you have a lsd without a belleville spring that was built with the right assembly clearance this is ok if you will have it rebuilt on a regular basis.
i also like to build racesetups without springs but with some preload generated from the clutches themselves. if you measure this setup you will also have a certain amount of preload but if you open it, there is no belleville spring inside. these are the quickest reaction setups out there.
there are so many tweaks you can tune a clutch type lsd. each one has certain pros and cons.
