Mine chatters an insane amount and like Sebastian said stop and go traffic is a big annoyance I'm going back to OEM once this one goes out
I'm not sure if they make stage 2 clutches that are compatible with OEM flywheels but I haven't looked. I don't see a reason for replacing your flywheel with another OEM one. My stage 3 clutch chewed up the aftermarket flywheel that was on the car and I was able to get it resurfaced here in town at some place right by the fair grounds.
