Nissan 370Z Forum - View Single Post - JWT clutch is just too damn good... unfortunately...

I did a quick search of the thread, but I'm wondering if the stock master cylinder is made out of plastic or some plastic composite material. This is the case on the Evo X, and people seem to blow them out as soon as a stiffer clutch goes in.

If so, this must be a common cost saving item with manufacturers. Metal is clearly better for something like a master cylinder... kind of disappointing for supposedly race-capable sports cars to have weak points like that.
