does your aftermarket clutch/flywheel combo make a rattling noise under 2k rpm? what the hell causes this? is there any fix?

If it does not chatter, what combo do you have?

 

no chatter at all....

JWT Flywheel / SPEC Stage 2+ racing clutch

 

Read my sig.....and I voted yes

 

i believe the JUN flywheel does not produce any chatter.

 

Spec Stage 2 with JWT flywheel an chatters all to hell below 2 an half. I've had the trans replaced an two different shops look at it both said its a loud throw out bearing supposed fix is putting the stock one in with the aftermarket parts.

 

very normal...and nothing you can do about it. I beleive there are quite few posts already covering this.

 

someone told me it was the throwout bearing too. I'm curious to know, but don't want to pay to have the old one put back in.. -mine chatters below 2.5k rpm too.

 

clutchmasters stage 4 clutch and lightweight aluminum flywheel....over 5k NO CHATTER

 

JWT combo here...chatter isn't all that bad at all. I alway keep my RPM over 2400RPM so I rarely hear it.

 

That chatter is worth it for the grab the aftermarket ones have, i love it as long as its not broke its all good with me.

 

i dont believe the chatter is from the throughout bearing, mine does it and it is stock. ive been told by two different stealerships that it is just a noisy input shaft and there is not much you can do about it.

shi*y

 

yes, cm stage 4 with cm aluminum flywheel and yes... theres chatter at low rpms. lol my car sounds pretty ghetto until it takes off.

 

I remember a thread saying its due to a unlubricated bearing in the rear axle. ill look for the post and post it here if i find it.

good luck.

 

mine chatters only below 1000 rpm so i voted yes...but i rarely get it. I have the ACT R6 solid puck/unsprung, with a prolite flywheel...but uh..that clutch is violent..but so so good.

 

mine is stock and it chatters all the time.

 

One thing you can do, is to switch to a heavier gear oil for the tranny. I switched to Redline MT-90, which is a 75W90. It made the tranny a lot quieter.

 

Is that safe though?

 

^hes right. Switch to redline MT-90, and change the diff fluid to royal purple. Much quieter, no more shaking when rolling up hills or reversing. Cleaner shift also.

 

This was taken from another forum explaining why there is "clutch clatter". Here is the link....

you need to understand WHY a trans will "chatter", the clutch doesn't chatter with a LWFW, it's the gears in the gearbox that you are hearing.
With a heavy flywheel, there is enough inertia to eliminate the gear lash, because there is always a positive force on thee gears holding them tight against eachother.

With a LWFW, there is not enough inertia, and what you are hearing is the frequency of the pulses of the cylinders firing, and each time one fires, it pushes the crank, the crank turns the flywheel, then the input shaft and connected gears.

Think about 2 gears together, there is a little bit pf space between the teeth of the meshing gears, this space allows a little play, "lash", and the gears will "tap" whenever a force is applied.

SO, long story short, a lightweight flywheel, which doesn't have the inertia of a heavy flywheel, will not turn at a constant speed, and therefore the "play" in the gears allows them to slop around a bit.
But with a heavy flywheel, the inertia keeps it moving at a constant rate, even between cylinder firing, and therefore there is always a positive force against the gears, keeping them in contact with eachother.

 

i dont even have a Aftermarket clutch and mine chatters loud enough for me to hear it with my windows up.
