Sounds unusual that the fingers are moving but the clutch won’t disengage.
Don’t take this wrong… Is there any possibility that the disk got put in backwards ?
I think it can be done and the result would be that it would hit in the center of the flywheel and bind on the surface of the pressure plate, it wouldn’t disengage even though the fingers were moving.
I was told that the disk needs to be 10mm thick when I did mine.
I used the Sachs aluminum 935 pressure plate ($1400) and a Cluthnet organic street/track disk, my disk measured 9.25mm thickness and after only 600 miles has started to slip a little when the boost hits in 3rd,
I’m not sure if it’s the disk is too thin or not enough clamping force by the pressure plate, the plate was suppose to be good to 700hp.
Keep us updated to what ends up working for you.
