??? what do you mean when you say you have to give it m ore gas? that the pedal is stiffer or that the response isnt as good

 

Not as much momentum on the engine so the car is easier to stall. Feels like you lose 10% of your torque coming off lights. In reality if you step on it at all the car is a bit quicker.

 

and how noisy is it?!

 

^^ yeah, looks like it's a SOLID flywheel. HOW NOISY? Unbearable? Worth it. One guy who has the nismo says it's unbearable and embarrasing and he's looking for a stock one. Wondering if JWT is the same?

 

I imagine it would be the same as the pre-07's as far as noise.

Its loud, a bit annoying especially outside the car once the tranny is up to temperature (about 15 minutes driving) and I personally am annoyed with the sound. But, having the only apparent option for a stronger clutch being this route, I would live with it

 

Just had mine installed

All I can say is that this is a very good mod for a z car.

HR revs-up very quick now and it feels like it is easier for it to push the car forward.
Chatter is minimal, and can be avoided completely by doing a more aggressive launch.
Drivability is not compromised at all. I don’t think you need to rev harder to get moving like it was stated earlier.

So once again, great mod and since I was doing a Slave Cylinder at the same time I saved $ on install.

 

^ my car is far from stock, so what i hear may differ.....

also , did I say I love my clutch now ? It is awesome !

 

so you got the clutch with it as well? I just got the flywheel in the mail today but am gonna wait till I get the clutch to put it on. How does the clutch feel now?

 

i only got the flywheel ... my clutch is almost brand new and grabs well now ( with the new slave cylinder )

 

Same thing i'm doing. 2200 miles on the car and no need for clutch yet just upgrading the fly. Dealer ordered the slave parts over a week ago and I scheduled for install today. I just got home and the slave parts still haven't come in yet. WTF? The recall has been out for awhile now why can't they the parts shipped overnight? I will upgrade the clutch when I do FI.

 

^ the parts will come... it does take a little long, but it is sooooo much better now ! yay !

 

awesome Ive only got 4k on mine so I guess Ill do this and wait a bit for the clutch.

 

this is why there is more noise with a light flywhell http://www.uucmotorwerks.com/flywheel/gear_rattle.htm

 

how low of weight until you really have to try hard to take off i need a cluthc and fly wheel for my car and I was quoted 850 for flywheel and 520 for a clutch its exedy but man tha tis expensive.

 

Its all relative.

I just ordered the JWT stuff and have driven my buddies 06...drives more easily than stock with much smoother performance. I've driven BMW's with 8.5 lb flywheels and they are just different. Once you get used to it there isn't an issue - you just can't drop the clutch as quickly without giving the engine some throttle.

 

what are you talking about... You can get the JWT combo (clutch + flywheel) for $775......

I got the Z back a few days ago with the JWT fly installed and slave recall done. I get this slight grinding chatter sound when taking off slow from N-1st. After that no sound.

 

Stock clutch or the JWT?

 

10-4, that is normal.

 

Stock. It's only when taking off from a dead stop and it's pretty loud. People outside around at the time look at me like my Z is broken. It goes away around 3k or shift to 2nd. I guess this is the noise people were saying was going to happen when losing the dual mass?
