Vibration in clutch pedal?

[Manual Calais]

I just got a rebuild on my t5 in my vn, and new clutch, put a excedy sports tuff clutch in as well, since i did this every time i hit 2.5grand it vibrates in the clutch pedal but only on 2.5 grand, in every gear, what would this be?

possibly just a harmonic/off balance issue in the engine being transferred back through? is the free travel adjusted correctly so the thrust bearing isn't continually riding the diaphragm spring?

i woudlnt know, i got it professionally done, im wondering if its bad and will it cause more problems?

possibly take it back and query them about it, if they can't fix/answer what it is a 2nd mechanics opinion wouldn't hurt, def sounds like a balance issue can't say for sure without seeing/feeling how bad it is it to tell you if it's going to be a problem or if it's nothing to worry about
