I have about 22K on my X, and the one that is worn out the most is my clutch pad. It is not worn through to the point where you see the metal, but it is worn enough that the pad is slick smooth. My foot slips from time and time, and the last thing I need is to blow out my clutch because of a rubber pad. Thanks for the feedback, and I will check out the Nismo website. Cheers.
