The chatter at idle from a aluminum flywheel most of the time is from the bolts shifting or biting into the aluminum after the 1st engagement of the clutch making the flywheel bolts "loose" Ive installed a dozen or so and started using red locktight and never had a issue with rattles or chatter at idle

Went with a chromoly forged steel racing flywheel. Weighs 13.6 pounds. Matches perfectly with the ACT 6 puck HD clutch and pressure plate rated for 650ib of torque. Little over kill but it feels AMAZING.. I literally start 1st gear with 2000rpm. Smooth engagement and no shutter feeling like my last clutch. I haven't done any pulls or launches. Still in the 1200 mile break in. see how it goes.

I saw this vid years ago. Can’t believe I came across it again.

chatter? Did you upgrade to a non sprung clutch?

i dont notice a difference but i went from a frame to a lightweight clutch and stage 2. never felt the stock flywheel

when you rev it in neutral does it make a sound? like it's free spinning almost it happens to me only when I rev it. I was told it's normal but I'm not too sure.

I don't have a chattering sound from my lightweight flywheel

What did you adjust in the ecu to help the vehicle come off the light easier? @4:15

You earned a sub when you said hide yo guns so causally when you seen the cop 🤣

Decent review but wished you would of touched on the performance end of it thou as when I added my light weight flywheel and new clutch I was pretty surprised let alone the revs were faster but the car itself was substantially faster with new single mass and shark injector software.

people say smf stresses transmission, is that bs? is the noise just noise or damaging noise..?

Thank you for your input. I have decided not to get one. I also heard it lowers torque idk how true that is?

Only downside to the Fidanza is I've heard the ring gear sometimes breaks free due to a failure, then you have to push start the car.

Torque when going uphill will be afected to. It will not hold the gears at the same rpm as it did with a heavy flywheel.

How did you get the bmw turned updated

@ZentRose Orange county like Orange County California or Orange Country central Florida?

i did that with my 94 civic with a few other upgrades, and mine runs quite. didnt have a chattering problem. i also installed a stage 1 clutch with that flywheel.... kept blowing through my stock clutches.

Can you please post some specs: model year engine, trans, what clutch setup from gripforce and more about how you needed to update your software to compensate for the bogging. I have a gripforce chromoly 14lb flywheel with sprung hub clutch just waiting to go on my e34 m50, I would love to hear back from you

I ordered one sachs lighweight for my audi rs4 ;) looking forward too test it out :)

Cool vid. Just curious what do you do for a living? Car related at all or completely different?

light flywheel is better, makes your car zippier. 0-60 will improve.

Excellent video man! I just did a lightweight flywheel on my 02 330i and I love it. I have noticed the car is a little boggy on take off. Did you get the new tune at the dealership? Or was ot a new ecu? My problem is I live in MT and the closest dealership is in Colorado...

I can add my two cents. when i got one it was really hard to adjust to it for probably 3-6 months. A lot more stalls and even now if I'm flustered it's easy to stall. It's harder to hit that sweet spot rpm because it revs quicker. It does seem faster to accelerate. you have to be quick at shifting to match rpms but i never had much trouble with that since I always shifted fast anyway. haven't really noticed the uphill issue being weaker. In my car it has the toyota version of vtec which means it gets a lot faster at high rpm so i believe this means i probably have a fair bit better 0-60 than stock but i haven't really measured. It is absolute death in very slow traffic however. like in absolute going at a crawl gridlock I want to kill myself. I can ease out the clutch in first with no gas and not stall it but it's *very* borderline and shudders a bit. never noticed any chatter so i'm not sure what that is about. My overall feeling is that the car does not do as well when you go slow and it's happiest when it's going fast.

I’m sure a well balanced flywheel/clutch will reduce the chatter quite a bit

No wonder my car is so zippy and accleration happy on the highway.

I've got one and it's so noisy man haha but worth it

can i fit uuc 6 speed manual Lightweight Flywheel on the oem clutch?

That noise is not from the flywheel it's from the throw out baring

Rattle noise is the same as a dual mass flywheel

not sure about that light wieght wheel.i know the dual mass is smooth due to it being 40 lbs and balanced.those 4.4 motors dont mind working a little.

Thanks for your videos..

What a yawn, sounds like he's darling asleep as he's talking about it

so do you need a new tune when you get a lightweight flywheel

You notice better acceleration with it?

I daily drive my e46 M3 in Ny.. there are times when i am bmper to bumper..sitting in first/ second gear. do you think it would be doable?

somehow dat dude is funny af.

Before Dual-mass all we had was standard flywheels.

Did you do the install yourself? What did it cost you

It's not the light weight flywheel that is the problem, it's the super grabby clutch that'll do you in. :D (What's the point of the light weight flywheel if you run a stock clutch anyways?) Removing rotating mass is a good thing if you like to hit the pedal. :) Less power used to spin heavy things = more power to the ground. P.S. The clutch and the flywheel are not the same thing. P.P.S. I have a 9lbs flywheel with an ACT clutch. Daily isn't bad as long as it's highway miles.

Do u experience a bit of vibration when ur in a higher gear an ur driving a bit too slow for that gear ???

is it make your car faster? because flywheel directly bolt on the crank and less weight on the crank less preasure on the engine and more hp can we say that?

Chatter could be caused by your throwout bearing.

Is this a lightweight flywheel and the lightweight clutch? Or just a lightweight flywheel and you keep saying clutch? How about Bucking in first gear during slow Maneuvers in parking lots or stop and go traffic? Does it solve rev hang issues?

Coudnt the chattering be caused by inbalance inside of the engine?

Thank you, Joe Bonamassa

Hey man, any chance you could point me in the direction of a single mass flywheel?

Never had a chatter with any of my Hondas. For a daily driver you will not notice a single difference. How often do you race that car?

In the original video you install a non spring clutch. So may be that's the problem???

Anyone knows about fuel efficiency on a lighter flywheele?

How much lighter is it? Were did you bu yours? Cost much? Just bought a Focus ST170 with 120'k miles on stock clutch... :)

You should mention what car you're driving.

Correction.... Your light weight flywheel has chatter lol..

I know your pain. but the chatter is to much lol I'm gonna go back to a stock flywheel next time.

there's no reason why a light weight flywheel would chatter either its the throw out bearing, pilot bearing, slave cylinder and some other things that revolve around the flywheel that would cause chattering

Would be great if I didn’t have a 6puck would be great it fxcking chatters like hell

You chatter because you have a organic clutch. 6 puck don't make chattering noise..

A single mass flywheel isn't automatically a lightweight flywheel.

pointless to have that on a daily driver 🤷‍♂️

Lightweight clutch lol, Btw a lightweight flywheel does not make a chattering noise.

that things a piece of garbage, glad i ordered a stock flywheel for my rb25

I have a 05’ e46, it’s actually a ZHP package. I have a stage two Dinan tune, and a extremely lightweight fly wheel. I mean extremely light. (Better for roll racing) And I barely notice a difference driving in traffic. If you know how to drive a clutch well, it won’t be an issue. But maybe if you’re starting out in a car that has a lightweight fly wheel, just remember don’t be afraid to use the gas a little more. But also remember if you wear out the clutch and the fly wheel, it is expensive as fuck to replace. It’s gonna cost five Gs to replace mine if it goes out.
