While the flywheel size (diameter) and mounting may be the same, they are different part numbers. Unlike the TO bearing which is the same part number.
Could be the STI flywheel is lighter, I dont know, but something is different about them.

The STI flywheel part number has been superseded to a different part number for some reason and they do look identical but do not match the part number of the spec b which has not been superseded to my knowledge. I have had both of the STI flywheel numbers
