I had my spec stage 2 and specs steel flywheel installed about 1200 miles ago and i recently had the cat removed and no off road pipe. I never noticed it until 100 miles ago but the clutch pedal vibrates real fast like a foot massager when driving but i cant feel anything when shifting . Its consistant with engine rpm's so im not sure if its just from the motor or from the tranny. should i be worried

 

I just installed my ram hdx clutch and noticed the same thing. I don't know about your TOB, but the outside casing of mine was not completely round. at one point it had a ridge. my theory is that this is the vibration. this is honestly just a guess though!!

 

your just feeling harmonic's through the pedal.. It's not uncommon.. could possibly mean your t/o is going as well.. keep a ear out for erratic noise's.. when you push the pedal slightly does it go away?

Edit: I see you don't feel it.. So i'd not worry about it till a issue arose otherwise..

 

Dont the clutch kit come with new throw out bearings? I dont know anymore, there are so many rattles that i dont know if its something to be concerned about or just my dash vibrating loose.

Edit: what is the t/o that you were talking about.
