clutch question

Okay so I made the mistake of buying a used clutch last year and at first it worked fine but this year when I tried to drive the car after 15-20 minutes of driving I can rev but the car wont move. So I came home and did the old 4th gear test. I stopped after a drive, put the car in 4th and let out the clutch to find out the car stays on and doesnt stall! so I knew my clutch was toast.

anyways I took the clutch out and this is how it looks.

now I believe and the people I’ve shown this to believe the disc is done but the pressure plate is reusable and I want more opinions on the matter.

by the way this is a nismo 350z clutch disc and pressure plate. its being used on a ka-t with a rb20 flywheel.

Well your pics do suck, but it dosn’t look like the clutch disk is fried enough to be slipping that bad. Could be wrong.
