I have 60K on my car now and the clutch was replaced at 20K something because of cold morning chatter. The "new" stock clutch was noticably softer than the old stock clutch. I am used to it now so I am sure if I had the origonal clutch back it would feel harder for awhile.
Either way, both were a lot softer than my other car so it never really bothered me. It was more of soft and softer.
Peace,
Greg
