I don't have a direct answer, but I sent my race car's flywheel to Top End Performance and had them lighten it.  I recall that they took about 9 lbs. off going from 25 to 16.  I installed a new OE spec Exedy clutch and it works great.  My engine makes around 200 HP at the flywheel.  It has about 20 road race hours on it and everything is good.  I think they charged about $175 plus return shipping at the time or something like that.  It was well cheaper than buying an aftermarket flywheel.

 

UPDATE:  I just checked TEP's website to verify my numbers and their long-time machinist died unexpectedly last week.  They are no longer offering flywheel lightening.  I'm sure you could find a local machinist who could lighted your flywheel.  The prints are available on the internet for the cut pattern.

I installed a Centerforce clutch kit with my aftermarket light flywheel.

Never any problems with mine. Not sure what they are refering to.

Probably depends on the vendor and how they drilled and machined the flywheel.
