JWT Flywheel chatters as well.
As Jason said, all flywheels will chatter.

The lighter the more noisier.

I've currently got the Unorthodox Flywheel and JWT Clutch.
I'm very happy with the setup.
Yes, it's still noisy.
Weight is around the same.
But the difference in acceleration CAN be felt.
Especially in the lower gears.

Good luck!

 

Also, another thing to remember...


The ONLY 2 times it will chater is:

1. At Idle with your foot off the clutch. If you put your foot on the clutch it goes away. Also 40% of the time you wont hear the chatter at idle without pressing the clutch. (you can also push the shifter towards 3rd gear and it will quiet the chatter as well)

2. Accelerating in gear below 2500 RPM. Say you are in 6th gear at 2000 RPM at 65 MPH (what ever it is)... You press the throttle to speed up, you will hear the chatter... Solution... Shift into 5th, your car will opperate more Efficiently... But once you get over the 2500 RPM mark the chatter goes away... With the TILTON set up it is at 2750 when the chatter goes away... The JWT I think is about 2300RPM... but figure you should be staying away from accelearting below 2500RPM in a high gear anyway... The chatter is always going on even with the stock flywheel, only the stock flywheel dampens away all that sound...

 

Can the JWT flywheel go in the stock clutch?

 

From what I've heard from another UR flywheel owner is that his chatter stops around 1800 (better, to me). Is this true UR flywheel owners out there?

 

Yes.

The JWT Flywheel, Fidenza Flywheel, NISMO Flywheel, UR Flywheel, Aasco Flywheel, STILLEN Flywheel can all be used with the Stock Clutch.

The ACT Clutches, NISMO Clutch, JWT Clutch, can all be used with the stock flywheel or any of the above flywheels.

 

Thanks for the info. Will replace the clutch and flywheel at the same time if I decide to go ahead with it.

Did you replace the transmission oil as well with Redline when you changed your clutch and flywheel?
