^ Appreciate it guys. The closest thing to a one piece "oem" replacement would be the Nismo flywheel... It is made of steel -vs- the Stillen which is made out of aluminum with a steel friction plate insert that can be purchased separately later on in the event it is ever worn to the point of needing replacement.

Keep in mind that a straight up oem replacement is always going to be a dual mass unit. There is no lightweight performance dual mass option. With that being said, any single mass lightweight flywheel no matter what brand will have chatter. It's just the physics at work that where outlined in my previous post.

I will say from what I have read the Nismo is the most quite of all performance fly's mainly due to its close relation to the stock's flywheel mass/weight. I believe the Nismo fly is roughly 22 pounds give or take. Either way, your going to have chatter no matter what if the switch is made, so I figured what the heck; JWT 14 pounder it is.

My entire build is based on having a fast, fun and relaible street car. I will say this clutch/fly combo is very street-able and should work out very nicely. Lets just say I do not fear a traffic jam.

Break in miles are completed and it grabs and pulls very nicely! I do have a concern though that maybe some of you with this setup can answer?..

During WOT pulls and high RPM shifting when the clutch pedal is pushed in it creates a dull "whine" noise that the best way for me to describe resembles a TIAL blow off valve. I can also feel it in the pedal. During normal driving this is not existent.

Clutch fluid level is spot on and the pedal feels fine.

I have attached a video that best resembles the sound. It is definitely not as loud or predominate as the video, but the sounds is somewhat similar.

 

The only noise I have experienced is flywheel chatter, however I have driven other cars with lightweight flywheels and have heard the same thing while shifting. Sounded odd to me, but the owners have told me that it's never affected the driveability of the clutch.

 

Thanks for the feedback guys. I'm about to purchase my setup, and this info is important. Thanks again!

 

Everything is fine like you stated. Just that noise. No grinding or vibrations. Gear changes are smooth. Just at high RPM shift changes I have that odd noise. She definitely gets sideways easy!

 

i have a stage 3 w/ a lightwieght flywheel and it always chatters but its an easy thing to over come..if its really that serious...... i heard it less after the exhaust.....

 

^ chatter is definitely livable and I have gotten used to it now, so really don't pay too much attention. Exhaust does help like stated above.

 

Ive got my clutch heading out pretty soon...slips in the higher rev range when under heavy throttle...

the jwt clutch flywheel combo is what i have been looking at as well and is in the "lead" so to speak...the price is right and it doesnt seem like it is too much of a workout compared with the stock...

although i dont have any huge horsepower in my immediate future, i would like a clutch that can handle some extra torque/hp

at what HP level does this clutch become an issue? 400whp?
