to me it doesnt make sence to build something that still takes up space (slave cyl) its not like the clutch will be super easy to pedal just because you go hydraulic.
The friction lost in a stock setup is minimal, and the geometry when properly adjusted is actally thought through by mopar.

Without having limited space and/or super heavy springs in the pressure plate a hyd clutch TO ME is a waste of time.

Newtons law "what you earn in force you loose in distance" applies to hyd too.
Aldough i have been thinking about some hyd/pneumatic booster.
But to me i only have limited space so its not gonna happen in a near future
