i just got my competition stage 2 clutch and light weight flywheel!! only on deceleration from about 3500rpm to about 2500rpm my clutch pedal and car vibrates ever so slightly! how worried should i be about this????? thanx in advance!

 

I think some clutch buzz is ok. I even experienced some clutch buzz in my stock clutch too. Maybe clutch buzz can go away after the break-in period.

About the vibration , you can try changing the clutch fluid.

Btw whats the weight of your flywheel ?

 

I have the same thing going on with my new ACT clutch. I've been told though that there is some sort of adjustment bolt underneath the dash by the clutch pedal that can help this. It's in the Helm's Manual, which I don't have. Try taking it to the place the installed it and have them take a look. I'm going to bring mine in this week and I'll try to give you an update.
