as far as i know they are already out...
600130 is the part #
they weigh 8.8 lbs, are chromoly, and should be pretty nice...

i have been told that an 8-9 lb flywheel will free up 5-7 hp. i know for a fact that the rev's drop ffaster though, on the CM flywheel i havfe i saw rev's drop 500-750 more rpm on shifts...had to speed up my shifting to not drop out of vtec.
