Question about Flywheel's
 

Does anyone know what the stock weight of a GSR flywheel is? I'm looking to do a clutch and maybe a flywheel. Most of the flywheels I'm finding weigh about 8 lbs. That seems like it might be to light....

Any help would be great.

for the LS, RS, GS, and The GSR it weighs 18 pounds and the type R one weighs 15 pounds

My stock GSR flywheel weighed 18 lbs, although some say it weighs 22; it weighs 18

So is 8lbs. too light?

i have a spoon 9lb flywheel. it works wonders.

8 lbs is fine, I have a ACT Streetlite 12 lb on mine though. I also had it on my other GSR. Too lite of a flywheel is known to make your engine stall sometimes. I have heard 12 is the way to go, but I've also heard every lb taken off the stock flywheel (18) is 2 horsepower to the wheels. (not sure if I believe that, but hey)

it's a matter of preference. You'll notice the revs drop faster in between shifts and it's a bit harder to slip the clutch to get going on a hill. Some can deal with it, some can't. You have to give it more throttle than usual to get the car some slip in the clutch.

I have a ACT Prolite flywheel, which is 8.8lbs and it took about 2-3 days to get used to it....after that, it's all gravy :)

I don't know about the exact numbers, but there is some truth to it.

remember that we're talking rotational mass here. I'm not going to go into the details of rotational mass, but it's not the same as taking the front passenger seat out to save a few pounds.

I have a 7.5lb Fidanza flywheel...I love it. The difference is night and day.

When it comes to flywheels, there never is a "too light"...or at least when given the options on the market. I would go Fidanza or ACT, whichever you can get a better deal on. Theyre cheap, well designed, well constructed and at ~7lbs are about as light as they get, aside from Comptech, which is more $.

You'll get used to whatever flywheel you get. Any issues relating to stalling will be identified and corrected within 15 minutes of driving the car. It will drive differently...rev faster, therefore you have to engage it a bit different. There are no intermittent stalling issues or anything, you just have to get used to it.
