Funny this popped up in my email....I just had my FX300 installed yesterday ;-) Glad you got a replacement!
Love the pedal feel (way lighter than my ACT street), and engagement is just fine (a little quicker but great location (about mid way through pedal travel...what I personally like) and already expected a little quicker engagement).
I might do a review later.
Had lots of hot spots (at least from what I think they look like...will post pics sometime if I get time) on flywheel. Clutch was slipping in cold weather, 4th gear. Started to get some pilot bearing squeak so I just pressed on with replacement as I had all the parts sitting at home (new WRX flywheel, FX300, upgraded throw-out bearing).
