That's what it is......gigged that **** up myself . It is a little violent on the street from time to time,but once you beat on it a little it smooths right up. I've been using the cintered iron discs. I may try some carbon ones next.

I literally couldn't tell any difference at all with my 18lb fw. Doesn't rev faster or anything...

If you've gone from a 28lb to an 18lb you sure would know & feel the difference in throttle response.

I threw this around in my head for weeks before I ordered my monster level 3. I ended up with the 28lb. My car is mainly a drag car with a spool and I know tooling around in the pits And around town I would probably smoke the clutch with the lighter one with tight turns and the binding of the rear.

Not at all, unless SNL didn't install a 18lb like they were supposed to...

Or if there was an 18lb fly already fitted before.

I think you would be able to tell the difference of 10 pounds

I highly doubt it had an aftermarket clutch or fly in it. I bought it with 23k miles on it bone stock. And this new clutch grabs a hell of a lot more than what was in it.

Nope not at all, I was very suprised. I was expecting a big difference and couldn't tell anything besides it grabbed harder and quicker. Doesn't seem to rev up any different then before.

You seem dead set on there not being a difference.

1, If you had a 28lb fly before & they fitted an 18lb fly...believe me the rpms do increase quicker.

2, They didn't fit an 18lb fly.

3, doesn't matter what weight fly was fitted as you don't have the ability to determine the difference.

Don't have the ability to tell the difference?? Ok yeah I can't determine that my car revs any faster. Because it doesn't!!!!! It really doesn't seem to rev any faster than before. If it does than it wasn't enough gain for the extra $$

Are you even sure they installed the correct flywheel? Just saying, you had a shop do it. The Monster level 2 clutch package comes with choices of either oem weight or upgrade to 18lbs so their is a slight chance there was some mix up. Notice how everyone but you can see a difference in a lighter flywheel...

Yeah I know everyone says there's a difference but I can't tell any. Maybe they did put the wrong one in it. SNL who is also monster did the install.

If you went from a stock flywheel/clutch combo to the 18#flywheel/Monster clutch combo it wouldn't be a 10# difference it would only be a 4-4.5# difference because the Monster pressure plate is heavier than stock. I would expect a that you would notice your car reving slower with the 28# flywheel because then you flywheel/clutch combo would weigh 6#'s more than stock. I hadn't driven my TA for almost 6 months because it had a bad slave cylinder so I can say I noticed much of a change either, but I might have if I have driven the car more recently.

I had a monster stage 2 with 18lb flywheel and did not notice a difference in performance. I also took it to the track before and after with no other mods done and gained nothing except i had to gas it more out the hole cause it bogged alot easier. I also had to give it more throttle comming out of first during normal driving which was annoying. I replaced that with an ls7 clutch and ls2(i believe) flywheel and like it much better.

Yeah I'm the same as you can't notice the lighter flywheel really and def give it more gas to take off. I'm so used to it now I'm happy with my monster lvl 2.

running a stage 3 28lbs flywheel from monster, no problems at all i love it, car is stock, a lot of clutch chatter but !!, when driving you can feel that it's really bossing up in there, i'd recommend a 18lbs for a stock car but not for a modded one

I've seen dyno charts long ago and the lightweight flywheel would free up power through the entire power band. Top end was usually 7-9 rwh

I've heard that too. I can't say I've ever seen that with mine but it does make the car alot more responsive.

rotational mass decreases.... so I could see that happening
