Clutch balance

I was wondering the same thing. What are the tolerances? I have one weight that is .3 of a gram difference and I didnt think that would be a big deal but if I knew the tolerances it would put it in perspective.

Thanx Himark....I hope someone has some good info for us....The factory balances them on something too ....I wonder what that machine is and how that compares to the aftermarket?....Do we have any factory employees out there? Seems like it would take a high dollar machine to be accurate.....Help please....
I just talked to Myron at SLP and he said they use a static balance kinda like a tire machine I would assume. I asked him about my .3 of a gram and he said I should keep grinding on it to get it closer. He really didnt give me any good info to see how much tolerance they can have. Anybody have more info?

I cut weights to within a tenth of each other. Maybe a little overkill, but when you've got something spinning at 8000 rpm, a little means alot. Look at how on your car or truck you can feel when that big heavy tire and wheel is out only a gram or two, shakes the whole car. Now think about that on a light clutch spinning much faster. 3 tenths is a lot at that speed. FYI most clutch weights I weigh that are "the same" from the factory usually vary from -1 to +1 gram. My 63s are actually "62"s that I weighed and had to cut even more. So, I would also like to know tolerances and balancing practices on clutches.

PM indydan or brad (1200psi) I'm sure they could give you more info. They are two of the better balancing clutch guys!
I've had indydan balance a few of my clutches, he would be the man to talk to.
