Ken 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. Barry ---------------------------------------------------------------------------- ------------------------------------- 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? Ken
