i think its def worth it...revs way faster and the chatter is minimal imo for my cm/4.....

 

The clamping grip is night and day. I recently went to the track and I was launching on my slicks at around 5000-5500 rpms. I made 20+ plus launches/passes down the track and my JWT took it like a champ.

I was also able to pull off two 1.9X 60s in my fart **** N/A roadster.

 

i recently put on a jwt flywheel. dosent really chatter as loud as stock at idle. the one noise that got louder was the cement mixer below 2200rpm as stated above earlier.

 

I don't understand why our cars are so loud. I drove a couple 911 Porsches, one 07 Lambo Gallardo V10, couple 08 Z06's and they're quiet as sin (drivetrain wise).

 

I have the JWT flywheel/cluth combo, and its loud as hell. I was expecting some noise but this thing is just annoying. I love the increase in throttle response and acceleration, but Im debating on whether Im really willing to put up with it as I drive a roadster.

ladyzed, I know what you mean, I've had a couple cars with lightened flywheels in the past and none of them have ever been as loud as this.

I trust the shop that did the work for me, but it almost sounds like something is broken. Yes, its really that bad.

 

it's normal with the JWT flywheel. I thought something was wrong with mine when I first got it also. I always felt like ppl were staring at me at lights wondering WTF was wrong with my car. My idle is bumped up now so you can't notice it anymore.

 

they r quiet because they r not a RACECAR

 

my clutchmasters flywheel chatters like a biatch! lol, but it doesnt bother me at all, my 3" exhaust rules the noise department.

 

nexx yours chatters alot?? my barely chatters...hmmm...guess im too busy listening to the exhaust...

 

Can anyone tell me which is louder between the Nismo flywheel and the ACT flywheel?

 

i can hear it, its not bad so it doesnt bother me. just sounds different.

 

hey im new here just picked up my z with jwt flywheel, how do i turn the idle up because the chatter is getting to me already

 

raise the idle?

 

a reflash would be the only way.

 

I also just had a JWT flywheel and clutch kit installed! I dont notice any noise at all but my exhaust might drown it out a bit! I agree that if you dont want noise go back to stock! I had Altered Atmospere do my upgrade and Frank thier shop supervisor did all the work on my baby! He knows his stuff when it comes to these cars! I dont agree that all these kits will cause noise issues because I dont notice any at all! Maybe it just wasnt installed properly.

 

ACT.

Note that the Nismo is also still pretty heavy (22+ lbs) and the ACT is rougly 14 lbs.

 

Man I just installed mine today(ACT6 puck sprung with a stillen LW flywheel) and holy s*** talk about a kick *** when you let that cluck out. But I would have to add with the windows down It dose sound like someone is beating a midget with a bag of rocks, minus the screams. Dose anyone have any sound bites on this noise?

 

yeah, anyone got a sound clip? I only know about the whirring sound when letting go of the clutch in neutral when i'm in my garage. Wonder how a lighter flywheel sounds.

 

Ill see if I can record it tomorrow and see what I can get you for a sound.

 

hey just wondering if everything is ok with mine, if i sit in neutral with clutch out it chatters but clutch in it goes away, im assuming this is right, and then at low rpm's in gears gets a little chatter, and then downshifting a little whine while the revs come down while in gear
