Spec Stage 3 makes loud groaning noise on engagement

[ZO6Cam]

I've got a Spec Stage 3 clutch in my Z06, with about 3300 miles on it.

Recently, the clutch started making a very loud, somewhat high pitched groaning noise when it engages. It's most noticible in 1st gear or reverse from a stop. However, it makes noise every time I let the pedal out after changing gears.

Anyone heard of this before?

I have exactly the same problem on my SPEC 3. I posted an earlier thread about it somewhere, a at least one other person had the same problem. Like a groaning/grating noise everytime you change gear (especially in 1st). Not sure whether it's a problem or not. Changing my block soon and not sure whether to ditch it. If you hear anything, please let me know.
