Yea people shouldn't post unless they know what they're talking about, you'll just confuse people. The rc10-gt doesn't use springs, it never has, it probably never will. Its just got two little shoes stuck on two little pegs that flop around aimlessly but work like a charm

.......
I think over time they loose some weight little by little (all the fine dust when you take your bell off, thats your clutch shoes wearing) and after a while they'll become too light and will stick at lower and lower RPMs. Eventually it will lead to idleing wheel spinnage just like you and I have.
See, you talk smack, but then you say something stupid. Hi pot, I'm kettle. The lighter the shoes are, they
later they will engage and with
less force. Why else would people drill out (lighten) their shoes? It isn't about what your opinion on this subject is either; it is physics.
I started to lay out all of the equations to calculate inertia (getting the shoe to leave rest and contact the bell) and centripetal force required to hold it there. But it would probably be lost on you. Also as acceleration is added, the the inertia of the shoes increases proportionally (Inertia = Mass x Acceleration^2), and so does the holding strength of the shoe. Therefore the "more worn" the shoe (ie. it has lost some mass) you can clearly see that it's inertia is reduced. As this inertia reduces, the speed you need to get it to engage will increase proportionally. Again, therefore the lighter the shoe, the later it will engage.
I make the suggestion about the spring because who on earth would put in a decently strong mill like a .12CVR and leave the stock clutch, and we have not been told what is there.
