so I was wondering if the stock Flywheel was machinable to decrease the weight? And if so does anyone know if there is a template or such as a guide for what to remove?

you shave down the back side of the plate. from the teeth, flat across is a start. that will take about 4 lbs.
then its up to you to how much more you want to take off the inside at that same area. where it divots in, you just pull that concave area outward. make the outer wall a bevel like the inner side and at least a half inch from the starter ring, just to be safe. that would be another 3-4 lbs, depending on how much you do.
after that, it should be balanced at a machine shop. -
oh yeah, my avatar is when i did the work.
here is what i came out with. i wanted to go a bit deeper to smooth out the inside, but it was late and considered it enough.
this removed about 6-7 lbs... not more like some suggest.Attached FilesComment

That is awesome and wonderfully helpful. now all i need is to find time to pull my flywheel, i suppose i could use another one. When you say you shave down the backside of the plate, how far would you suggest I shave it down?sigpicComment

No known issues with shaving a stock flywheel? I saw the results of a tuning shop shaving a stock flywheel on a Honda and it exploded, suck on a RWD car if it exploded and pieces went through the bell housing into the driver's leg...Comment

from what ive read around the way, pictured is a safe amount to lathe.
there is always the risk of the disk fracturing, but pretty unlikely that it will actually seperate from the clutch and make it through the cars body.
when i say shave down the back side of the plate, and if you knew what it looks like stock, youll know what im talking about.Comment
