Clutch pedal is going to the floor and staying there. Is there any other reason for that to happen other than the master cylinder?

What year is your car? '07-'08's had issues with the CSC that was covered under warranty. Had mine go out twice on the track and replaced both times at the dealer no questions asked. Finally upgraded to the ZSpeed CSC upgrade.

I have an 07, Had a new clutch master cylinder put in due to failure back in Sept and it has gone out again.

Slave cylinder, or bulgeing of the rubber line.

I would start with a bleed, simple and usually works.

And after bleeding the clutch, see if there is any brake fluid leaking from the hard line to the CSC heat shielded line. Mine let go at the end of last season, when one of the double crimped ends just melted free. But if you find brake fluid leaking from the bellhousing of an '07-08 Z, there's a failure of the CSC itself.

i would do the slave and master from zspeed, or z1 just designed their own that is pretty interesting
