can someone break it down for me? i have a vague understanding of the two; sprung = clutch disc with springs, softer engagement, unsprung = on/off, rough engagement. if anyone could add to or correct this it would be greatly appreciated. also opinions on whether it would be good for daily driving are also appreciated. thanks.

sprung is most noticeable when dumping the clutch as it will spread the shock over a bit more time …
unsprung will not be on/off … you can still slip it …
sprung is a good idea because:
- it will reduce engagement chatter (severity of this problem depends on friction material)
- it will reduce crank vibrations
- it will be a little more gentle on transmission
unsprung is a good idea because:
- it will weigh less
- less parts to break
- because of above … more suitable for higher powered applications
If you are running SERIOUS power I’d suggest a non-sprung.
Otherwise … I’d stick with sprung I think.

I’m rolling on an un-sprung clutch, it’s not bad at all, but my pressure plate is weak sauce. It doesn’t chatter and I don’t really notice how different it is untill i get into a car with a sprung disk. It does that jerky shiit a lot when letting off the gas in 1st/2nd, not sure if that’s my solid engine/tranny mounts, the clutch or both…
Unsprung and a heavy pressure plate is a lot harder to drive, more chatter, more on/off feel.
And they’re just as pron to breaking since they have no give in them…

It’s probably the engine mounts and possibly your TPS adjustment as well from my experience.
