From what I'm gathering from all the clutch problems guys are having is its the clutch itself. With the weight and power of our cars the OEM clutch doesn't have enough holding power to not be slipping to some degree when used hard. This in turn overheats the assembly, boils the fluid (which is why the pedal goes to the floor) melts the release bearing support and then destroys the release bearing, which requires replacing the entire slave because it's one unit.
Changing the fluid helps-slightly, only because it keeps the boiling point up. The issue of heat is still there. In my case the release bearing and support went before I had the pedal going to the floor but I was changing the fluid regularly.
