Clutch effort & available clutch release travel have been issues since the first Pantera hit the road.
Lubricating the clutch pedal assembly is a definite first thing to try. If that's not enough, here's two ideas:
The hydraulic throw-out bearing sold by Pantera Performance Center reduces effort, as per one reliable source. And it improves the amount of travel available too. Perhaps others could chime-in on that.
And of course, diaphragm clutches are "supposed" to reduce effort too. What do you say guys, do they help?
