Unsprung and Sprung clutch differences
 

Whats the difference between unsprung and spung clutch? Looking to purchase a new clutch for my 370z that will be driven semi-daily whats a good clutch and where do you think I should go for ordering one?

If the vehicle will see much time on the street, go with the sprung. For a track vehicle, unsprung may be a better choice. As for the difference - Google is your friend.
