Torque to yeild bolts are "stretched" when tightened and must be
replaced. I don't think I've ever replaced clutch bolts - would on a
drag car, but they use automatics almost exclusively today

I'm gonna get the bolts but I don't think I need them, as you explained.
I'll get them because (a) they're only 7 bucks, and (b) Toyota says to use
new bolts every time.

But I agree that I can re-use the old bolts too, so I'll forget about this
for now as *choosing my first clutch kit* is the more important goal.

1200 lb clutch will build your left thigh muscle in traffic and will
grip a little tighter. Basically a truck or race modification (Once
I'm movong I generally don't use the clutch)

I've been researching this on the side and I'm still confused, but one
thing I learned is that the torque from an engine is only about 300 foot
pounds or less (278 foot pounds according to this quick search):
https://www.google.com/search?&q=toyota+4runner+torque+specs

So what I don't get at all, is if an engine only generates 300 foot pounds
of torque, why would we even need a 900 foot pound pressure plate, given
that the ratio of the flywheel diameter to clutch plate diameter is fixed
at what? Almost 1 to 1? Or is it 2:1 or 3:1?

How does this math work that a 1200 foot pound clutch does ANYTHING useful?


PUT AN OEM CLUTCH IN THE DAMNED THING AND BE DONE WITH IT!!!
