[DeTomaso] Clutch Pedal Reduction Kit with Diaphragm Pressure Plate?

[Ken Green]

Thanks Barry,
     I'll have to take the long throw slave into consideration. I haven't gone to one YET.
     What I was originally trying to get at is that nothing is free, and assuming the same amount of master cylinder stroke, the reduction kit can only redistribute the work from the end of the stroke to the start of the stroke.  If the pressure plate follows a simple F=KX relationship between force and disengagement, it makes sense to transfer some of the effort from the end of the stroke to the beginning.  But I don't think a diaphragm pressure plate is very linear, so the force near the end of the stroke does not follow a F=KX relationship.  Additionally, I think the more your leg is extended, the easier it is to apply force.
    Maybe do more squats?

I have a Centerforce Pantera diaphragm clutch. I have the effort reduction
kit and the Long throw slave in stainless steel.
The pedal effort is still pretty fierce. I would say maybe 40-50 lbs to
depress. I'm thinking of going back to the stock slave cylinder which will
reduce pedal effort at the expense of less friction plate clearance when
depressed. I seem to have an abundance of that.

  Given the mechanical characteristics of a diaphragm pressure plate, does
it make any sense to use a clutch pedal kit with one?  My recollection is
that the clutch pedal kit provides more leverage when the pedal is fully
depressed, but a diaphragm pressure plate does that anyway?
