Slight clutch pedal vibration

[Denji]

Hey guys, heres whats up...

The other day my friend with a 96 gsx told me that he was getting a slight vibration that varied with his rpms while pushing in the clutch pedal and so he called me and asked me if my car did it. Well, i responded to him with a no, that i didnt think mine did that. However, when i got back into my car the next day and remembered i realized that my clutch did seem to be vibrating as he had said. What could cause this? I'm rather sure its vibrating more than it used to..but then again perhaps its in my head. Also, i would like to emphasize that the vibration is not very bad, its actually pretty slight..but it is noticeable.

1. it has been between 30-40 degrees since i realized that i had this "problem"
2. car has no current driveability issues associated with this feeling in the pedal. The clutch grabs hard and engages at the same pedal height every time
3. my clutch was put in about 4 months ago, professionally, flywheel resurfaced and throwout bearing replaced with a mitsubishi oem replacement.
4. master cylinder replaced by me a month ago, fluid reservoir is full.
5. vibration predominately noticed while depressing the clutch

Thanks for any help, please tell me if i am just focusing on it now and i think i have a problem when i dont, or if i really have came across something significant- Brandon

yeah, it feels a little more like something needs to be lubed than anything, i put some rubber grease down on my master cylinder and that was no help, so if i lube the clutchfork pivot ball that should help...okay...well may i ask what in gods name that is? I will try to search in the meantime, update me if you can explain to me.

Thanks for the responses so far, keep them coming please!

P.S. i have noticed no unusual sounds along with the slight vibration (in other words, i can feel it but cant hear it at all).
