Clutch Scraping Noise

[Asmodeon]

Hi guys for the past few months my R32 GTR has been making a scraping or grating noise when releasing the clutch. The noise only becomes apparent after driving for more than 10mins. The clutch also feels it is gripping some what when the noise starts to occur. As far as I am aware the clutch is the standard original but I have not yet taken it to a clutch specialist to get things checked out.

Anyone have any idea what the possible cause could be to this noise?

sounds to me you have a cerametalic clutch in it.
