Clutch Slipping

[mikeroy420]

I have a SPEC stage 3 clutch with a fidanza flywheel in a sr20det blacktop. The clutch works fine when accelerating until it hits about 4 on the tack then it starts slipping, so far I have put 600 km on it, does anyone know what might be causing the slipping?

Thanks

when adjusting clutch pedal, where is the best position for a new clutch? could this be the problem?

the clutch is not fully disengaging. there is a threaded bar that comes off of the master cylinder adjust that bar to give the pedal some play.
