Why its a good idea to buy a sprung disk clutch Options

I stumbled on this video from Exedy on how a clutch works. Pretty basic stuff but the most interesting part is in the second half of the video that explains the function of the springs in the clutch disk and why sometimes we hear a rattle at idle with performance clutches.

This video goes into even more detail on the clutch dampener.

I think based on this, I will never buy an unsprung disk again. The spring dampeners are a very important thing to have!

The only downside is that sometimes the springs fall out. I believe that this is mostly caused by us using clutches with much harsher friction material than what we actually need. When the clutch engages, it puts too much stress on the springs and they end up popping out. The best solution to this problem that I've seen so far, is to encase the springs in rubber. This is done on a few OEM style disks but for some reason has not made it into aftermarket performance clutches.

That's right, your JDM car deserves Japanese made parts. It's only logical.
