Think ive asked this before but with the forum issues of late cant find an answer... so here goes.
seen threads on other sites about flywheel skimming and lightweight flywheels, in regards to performance gains.
Is this just a matter of skimming the rear and taking out 25% of the weight?
is this easy to do or does it need to be a strengthened plate?
any guru thoughts out there....???
all the best

If I remember Bob's reply correctly, you have to do a lots of other stuff before you notice any real difference from doing anything with the flywheel, plus I don't think that it's going to make it a performance car!

Thought i heard a few years back that an MX3 Flywheel is lighter than the Probes.
Personally i wouldn't machine an original because if it lets go it will make a mess.
Think you can get Aftermarket ones in the USA.

I think I have a lightened one in the garage somewhere - I will probably fit it to the replacement engine when I replace the clutch

Aftermarket - it’s a Fidenza one if I remember correctly

Lightening the flywheel will make the engine more responsive because it has less weight to accelerate. However it wont give you more power. Power is power and you would need more fuel and air to increase it. The "responsiveness" downside would be that it will decelerate more rapidly too, potentially making gear-changes rough and notchy.
Then there is the balance issue. Remove metal and you run the serious risk of upsetting the balance of the flywheel, either through poor concentricity or through warping as internal stresses in the flywheel are released. Thus you would need to have it re balanced to be on the safe side.
Of course its your flywheel to do with as you will, but my thinking would be that if the designers of one of the worlds biggest engine manufacturers decided that the car would work best with a flywheel of a certain weight, they might well be right!
