The clutch pedal height has to be raised, there is an adjustment behind the pedal, this allows more pedal travel into the clutch master cyclinder when the clutch pedal is depressed, thus giving more movement at the clutch slave cyclinder so that the pressure plate opens further (more dissengagement). I hope you get my drift This has all been covered before, I seem to remember that pictures were posted of the adjustments, do a seach, they should still be there.
