I'm really hard on my car, and wore out my clutch in 70k miles, wore out as in the rivets were wearing. I bought my ACT setup (Heavy duty pressure plate and Street/strip disk) and have had it in for 25,000 miles. So far, I absolutely love it. The pedal is a bit firmer, but I was used to it in a week, and actually prefer it. My car isn't very fast, but I can chirp third. It's super smooth engaging, too. I've adjusted it once so far, and not very much, so I think I'm getting pretty good wear. My only complaint is that it took forever to actually get. I'll heartily recommend it.
