Did you adjust the cmc after installing the clutch? You should only have about half an inch of freeplay so if your pedal moves half way before moving the fork I'm guessing you need to adjust it. I just installed a stage 3 comp clutch in my si and I had to adjust the master cylinder rod out quite far to get it to disengage the heavier pressure plate.

 

I did not do this, didn't even cross my mind but thank you for the info, I will definitely look into that and try to post an update on this discussion.

 

Update: CMC gave out during the adjust and bleed process, time to replace. Will be replacing soon, weather permitting. Update will continue to come along.

 

Are you sure the clutch was toast to begin with or could the cmc been the issue the whole time? I guess it doesn't matter at this point since you've already replaced the clutch but curious.

I'm dealing with a similar issue. Lost my clutch so I replaced it with a stage 3 comp clutch but two weeks later my cmc failed because the dampener broke. My clutch was definitely bad because the disc broke but now I'm not sure if the cmc was already going bad and caused the failure or if the heavy duty pressure plate killed the cmc. I swapped in the sirimoto cmc and slave and I'm hoping it will hold up with the stage 3 clutch but I'm having ptsd about breaking down again. Lol

 

Damn that sucks. If it goes through the gears good with the engine off but won't with it running it's got to be an engagement issue. Did you bleed the new cmc enough? I bench bled, gravity bled, vacuum bled and pumped the clutch and bled it a lot. First time I tested engagement it felt OK but not great so I bled it more then readjusted the cmc. Today was my first full 100 mile of driving day and it felt great. Now I'm just hoping it doesn't all of the sudden crap the bed on me again.

 

I'm sure the CMC did cause my premature clutch wear (old disk at about 5-10% friction material), and think I may have found the culprit in my current problem. I will get the part and try it before revealing, so that if it works I can give you the info and hopefully it'll help your car as well.
