Spec 2 bucking
slipping the clutch at low rpm's will cause more chatter than just letting out the clutch.
going to a more aggressive clutch like the SPEC 2 will compromise driveabilty somewhat but the clutch will hold more power than a stock one.
I would assume the clutchs become more aggressive as you move up on the SPEC's (2, 3, 4, etc.)
My $02 is you will find the sweet spot and it will chatter less after break in.
