I just went with what they recommended....
You know I don`t know much about this stuff. Yea it`s a T5-z with hydraulic clutch, I didn`t have any idea they made an external slave, I would have looked into it.
But it`s going good so far, I had to replumb my brake lines to put the clutch master cylinder how I wanted it. I installed a combo valve in the brake system at same time, got a good firm pedal now, first time since I got the car. The clutch pedal and hydraulics are all hooked up, that went fairly smooth although very time consuming doing mockups and teardowns over and over.
A guy that owns a muffler shop is letting me use his rack saturday to put my car on so I dont have to try this on jack stands, so I`m happy bout that too.
