So I got the Competition Clutch Stage 2 Street clutch with lightweight flywheel. It feels good so far, of course it'll be a few weeks before I can actually push it. Anyways, I'm hearing some pretty noisy clunky sounds between 1500-2500 rpm, mostly after starting in 1st from a dead stop. I can hear it a bit in 2nd too, but after that it's fine. Is this normal?

Is this clutch chatter? I thought clutch chatter referred to the noise it made when it was idling in neutral.

 

Lightweight flywheel = chatter/noise = normal at idle
Nothing to worry about :-)
