Re: Light Flywheel (steveNY)
See sig for what I did in this regard. I only notice any chatter if I use really low revs on launch. I'm now approaching 1K on it, no issues. Never had the shakes soem people are describing. I suspect a lot of it has to do with the whole package.
Balance is important. I bought the whole thing as an assembly, and it was balanced as such (cost me 750), so that may have been a factor in not having any shakes and shudders. I autocross very frequently, and it is definitely a help there.
As far as learnign to drive it again ... that maybe took about 10 miles? It didn't feel that different. I suspect some of that comes from most people moving to a non-stock-feel clutch at the same time. My new clutch feels just like stock.
I say if you do it, go for a new clutch at the same time given the costs. Also consider any other mods that involve taking the exhaust and/or torque tube and/or rear diff at the same time as all of them come down. You could save some money on labor by combining those upgrades, if you were to do them.

Re: Light Flywheel (JR04Z06)
I have one. No chatter at all, and it does rev a bit faster. The clutch/flywheel was bought as a package and balanced together. I had to relearn driving because of the dual disc clutch. The plates engage a bit differently.

Re: Light Flywheel (steveNY)
Did you buy the aluminum flywhell from Spec or other manufacturer? If from Spec, did it come as a balanced set or did you have to do that afterwards?

Re: Light Flywheel (SleepieAce)
From which manufacturer did you purchase your clutch and flywheel? What product did you buy (ie Spec 3 or 2, 12.5lb flywheel or ?) Would you do it again or not? I'm shopping right now and would appreciate your thoughts. Thanks.

Re: Light Flywheel (R6T2Corvette)
I got mine form Xtreme (see vendor links). See sig for what I got, they made the original clutch. Paid 750, IIRC. Would I do it again? In a heartbeat. It'll hold IIRC 525 pound-feet of TQ.
