OEM master diameter/throw? Working with a swapped car. Cd009 trans with a wilwood master and a standard T56 slave setup. Billet ICT clutch/trans setup to run the CD009 on an LS.
Issue I'm having is I have almost no range between fully engaged vs disengaged. Talking maybe 1". It's drivable, just not ideal. Changing pedal height just changes where that 1" is located. Was thinking maybe the master piston diameter and throw is just too much for the slave? I am using an3 SS line. Maybe the line is too small diameter wise?
Any suggestions welcome.

Is the ICT clutch known to be a lightswitch? It sounds like a clutch or pedal throw issue. Looks like Wilwood offers only one size smaller, 5/8. No detail about your pedals . .

It a factory 5spd 84 rx7 pedal. Seems to have plenty of throw. Its a T56 slave. Measured the installed slave height on install and it didn't need shimmed. Was within spec. IT drives and shifts fine. Just has diddly for travel between engaged vs disengaged. Pretty sure its bled well. But I can try again. Adjusting pedal height with master arm just changes where in the pedals travel engagement is. I have it at the middle of the pedal now. so I have like 2inches where it does nothing initially. maybe 1" where it disengages and then another 2" of travel to the floor where it does nothing.
Yeah, I see they list their disc as working with the LS bell, PP , slave, and flywheel. I have heard the RX-7 later gens carried a longer pedal throw. Sounds like you have pedal mods to do to match GM or 5/8 cylinder to try. Enjoy your swap.
