09 clutch issue

The stock Z is a "Sports" car, not a "Race/Drag" car, and it just can't handle rough treatment without modding money spent on weak areas.
I'm not trying to justify the plastic CSC, it should be more robust, but if that didn't break, something else would from the rough treatment.

What causes the Master Cylinder to fail? It's cheap I guess, and can't withstand repeated scraping of the O Ring in oil with clutch fluid nasties in it.
