Where to begin...
First thing in the morning, when the clutch is cold, it's a dream. After a few miles it's a bad dream.
Getting started in first gear is the biggest issue. Once you're moving it's actually a really nice clutch. But getting started goes like this: Hold revs at 2800-3000 rpm, COMMIT to letting it out and hang-on. It's really lovely on a hill or in heavy traffic where I tend to lack commitment and I end up with a level of shudder that I didn't think was possible. I have to believe that I've done things to the transmission that will require repair. There is very little room for error and the sweet spot is not dependable or consistent. (NF Performance did my clutch damper valve delete.)
It's possible this too much clutch for me and this is the way it's supposed to perform and the way some want it to perform but for me it has really impacted my enjoyment of the car. However, there is a growing body of evidence showing that these are failing waaay to early:
