Default Does aftermarket clutches chatter?

Mine does. I didn't change the flywheel. I just had it resurfaced but my clutch chatters a little sometimes. I'm scared my mechanic might have not tightened some stuff up.

They all chatter.---At least any 2JZ 5spd clutch that holds any power chatters. If someone has one that holds 450lbs/ft and doesn't chatter, speak up...

My HPF w/ ACT PP is silent. My ClutchNet on the other hand .. made all kinds of noise.

I am very surprised that the HPF doesn't chatter ... I have about 1,500 miles on it, maybe a few less, and it has been quiet the whole time. We will see how long it lasts.

Angel, just give it time, it will start to chatter. By chatter, I'm not talking necessarily about noise, but referring to the clutch shuddering on release. The HPF seems better in this regard than the other RPS unit, but is nowhere near stock smoothness. I get an occasionall squeal on downshifts (like rowing gear box down 4th-3rd-2nd when slowing.

With the HPF clutch you can typically get it to smooth out for a few days by doing an extended, high rpm (say 5000rpm) slow release of the clutch. The instruction sheet that came with the clutch advises this as part of the break-in procedure in the event that chatter develops.

Yah ... it doesn't do any of the jerking during pulling out from a stop either (wow, saying jerking and pulling out in the same sentence sounds bad, eh?)

My ClutchNet tho however, was a joke, almost impossible to drive the car. I am not expecting the HPF to stay like this forever, but for now, it is nearly perfect.
