I have about 25k on my front's and over 2/3 still left. I use the front brakes HARD and still very little wear. I will say however that about 1/2 way through my last track day, I wish I had changed them about 20k miles ago. They were almost useless.
They were weak and chattering. I thought maybe I was slamming on the lever too hard so I tried a lap or two with really exaggerating how slowly I applied the pressure - same outcome. Almost nothing, still nothing, very little, then BAM - full brakes, chattering, but squishy feel.
I'll be getting something more substantial and changing even though it looks like I have at least another 20k more pad left on the stockers.
