I am not sure if there is something wrong with my Spec III or not. BUT i can make it not chatter. When i let the pedal out really slow while in neutral...when the cltuch if fully disengaged it does not chatter. If i let the cltuch out normal(fast) it will chatter.

Plus...the chatter is a small price for me to pay to have a good grabbing clutch that won't fall apart like my stock one did.
