I just got my lightweight flywheel and clutch installed on my G. Under load my car makes a distinct rattle sound from about 1500-2500rpm and then stops. It seems like the clutch is making this sound or the flywheel may be unbalanced maybe? Can anyone give me some input on the subject matter. It would be greatly appreciated. Thanks.

 

lighter flywheels will make more noise, the stock flywheel had a dampener on it that helped with the noise...its normal

 

It's normal. You're going to have to live with it.

 

It's normal. It is called "chatter".
The stock flywheel is dual-mass meaning there are two parts connected by springs to dampen the sound. The lightweight ones are a single piece that allows all the sound to go through it.

It's not hurting anything. Mine does it too. The installer should have warned you before doing it.

 

Agreed. It might also go away after it's broken in. So make sure you break it in correctly

 

Wild. I just bought a new 06' 6MT and it does the exact same thing. Only in 1st, and only at low rpm's. Sound is gone by about 2500, and sounds like a rattle...

 

Purcha - Which flywheel/clutch combo did you use?

 

Same rattling noise happens on my 93 Vette. Went from dual mass flywheel ($1000 flywheel) to a single mass flywheel, (lighter and cheaper).

 

this is normal : ( it wont go away. my stock setup rattled a bit but when i had the jwt combo installed, it rattled even more.

 

if it really bothers you, you could dynomat your whole car to help dampen the sound

 

Yeah, and make an already heavy car a lot heavier.

 

It's no heavier than a Ferrari F430

 

And it doesn't have the go power, handling, sound, well, *ANYTHING* of the f430 either

 

i have had jwt flywheel combo on my car for about 4 months and it seems to be getting louder.. wonder why though???

 

The F430 has better power:weight, so that's not a relevant comparison
