So I have a 2005 Z with 26k miles on it, and it's NA. I'm thinking about going FI with a turbonetics kit REAL soon. I just drove my buddies 03 Z with a turbonetics kit (TN flash) and he has a stock clutch. The FIRST thing I noticed was that his clutch was MUCH more firm than mine, and harder to push down... Mine doesn't feel like putty or anything, but my clutch is noticeably softer.... I've also noticed that my car has a random "clunk" noise coming from underneath the car. I've searched about the clunk and it seems to be the throw out bearing...

So my question is, how can you tell if the clutch is going??? I don't drive my car hard AT ALL! Its my daily driver... I've been hearing the JWT clutch is a good way to go...

(And sometimes I notice that when I go over speedbumps and I'm feathering the clutch, the car seems to jutter a little bit when its engaging.....)

ANY help would be GREATLY appreciated!!!
