OP - Your chatter might have something to do with your new friction surface from fidanza. When i just redid my clutch setup i installed a brand new friction surface on my fidanza flywheel and took all my stuff to my clutch guy to have him look it over and balance it. When i went to pick it up i noticed that he had scuffed the friction surface up a bit and when i asked him why he responded by saying that the way it came was too smooth and uneven. And even though it was brand new it would not transfer material evenly, thus causing chatter.
Its just a little experience i thought i'd share as my clutch guy does have over 25+ years experience and was one of the founders of centerforce.
