For $11.00 dollars, I buy them by the bagful from Amazon...60 clutch pads, which is 4 change outs of clutch pads.
I never use the red clay like ones that come with most kits but replace them with these pads...Still have the original ones I put in to my Phantom over a year ago with no sign of excessive wear as of yet.

I agree with Jerry...Such a cheap item to replace and you rarely need to replace them, why experiment with a material not intended for clutch pad usage???
