i have about 55k on my original clutch and now that im sc, I think its really about to go. When i try and accel. even at a moderate rate i get a humming noise and also it doesn't feel like its propelling the car forward like it should. When i get off the gas after accel. The humming is still distinct, and it also has a vibration that runs through the car as well. How long do you think i can baby this thing around?

Your making a lot of power and your clutch can't handle it. Time for a upgrade.

Good Luck

same damn thing just happened to me. $770 (shipped) for new Stage 1 clutch and lightweigth fidanza flywheel
