Well my clutch is starting to slip alittle when im shifting really hard (yes the CDV is deleted) so i decided since the clutch is such a big job anyway i might as well and do it right considering i plan to charge my 528...
so here it is...
http://www.uucmotorwerks.com/flywheel/LFWLE46SH.htm
hehe... im excited jsut got to wait till it arrives and spend a solid weekend i expect to install

FYI: i opted for the e34 m5 clutch because my car will probly not make it over 450hp that the clutch is rated for...

I jsut cant wait for the RPMS to fly....................

The UUC flywheel should not ever look so good. Flywheels (were) ugly, but theirs is jsut teh sex...

These are not my pics... but enjoy!

Enjoy the rattle!

Dan installed one. The rattle would drive me insane if it was my DD. Changing to a heavier wt fluid and raising the RPM's might help with the rattle. I can't see the need for this flywheel unless it was without any noise and offered a noticeable difference.

I had one on my 01 330I with the vortech blower. I felt I needed it to help the Revs climb a little quicker so the boost would have a quicker impact. It may have helped, but your right, the rattle drove me nuts.....:mad

are you taunting me?
:shifty

Is who taunting whom?

are you taunting me?
:shifty

yes yes i am.........................


And please dont tell me about the rattle i have been crying myself to sleep thinking it wont be there.... heavy weight oil and holding the clutch in... that should do the trick!:redspot

That rattle will kill you inside.

Rosie O'Donnell's voice will be emanating from your drivetrain. :D

Only two people could withstand that rattle. Dan, cause I think he's deaf (srsly, talking to him on the phone is one 'what' after the other. Maybe cause he's trying to do 19 things while talking and with his free hand he's taking his blood pressure with the machine) and...Chuck Norris.

Other than Dan and Chuck Norris or dudes who use the car to race...good luck!

yes yes i am.........................


I knew it.... :shifty

I have the UUC lightweight flywheel in my M5 along with the stage II clutch, and the rattle is not bad at all. The rpms have been raised to 900 and it is acceptable. If the rpms are not raised, that's a different story... Enjoy!

I hear Both Dan's, and the other guy with the M5 at the NJ meet. and i can live with that. I figure with a supercharger and cams in my future i dont think a little rattle will make me mad. Plus i took my car to 3 track days this year, and several auto x's so i can stand a little rattle fore the RPM's hehehe

Yeah, that will do it..Just hold the clutch down every freakin time you are at a stop light, keep holding that pedal til you hear Rosie O'donnels voice squeaking at you! Gumbie's right, you might just kill someone..:D

...Be aware be very aware at the next e39 meet...

How much did you pay for the UUC flywheel?

Dan would never buy such a product. :nono

Correction: I would never let Dan buy anything. We have a stability clause. :lol

------------------------------------------------------------

As reviewed ad nauseum, the rattle varies from car to car - some none at all, some a little, and some moreso.

Drivers also vary. Some enjoy performance and figure out how (with the recommended trans oil change) how to reduce or eliminate the rattle (if there car even has any), and some don't understand that a change to the car is a change to the car and should leave their car all stock.

I support your mod. The rest are jealous, can't afford it or are afraid to do it themselves.

When my clutch goes I will be getting a lightweight one also.

Good luck and enjoy the h*ll out of it.

Thanks Franka, they are jealous of 39whp in first gear added to my little 2.8liter:alright

too bad i cant afford it:(, im broke now dammnit college and cheap jobs!

Let us know how it turns out James, I'm interested to learn how much it improves acceleration etc...

I want to get one for my 2.8 too when she goes out!

At least it's a pretty blue. Like a baby toy...what do they call those again..oh yeah...rattles. :)

Yes, we're all jealous of James' flywheel. I can't stand it myself - it's tearing away at me internally. Why must another man possess a flywheel that's better than mine (if I had one)!? Dear God, WHY!?

Good luck on the install - hope it's all you dreamed it would be. Also hope you don't get banned for giving a negative opinion about it on here. Poor Dan.

lmao :lol:lol:lol:lol:lol:lol:lol

BlackSapphire i heard Dan's at a meet and it wasnt too bad, do u know if he had his RPM's raised? Theres a guy near me in RI that i meet up with occasionaly, and he has a supercharged 330i, with the same flywheel, and his RPM;s are raised to 900, and there is NO rattle. Thats what im praying for.

I had this package in my 328 and I could only hear the rattle at idle if I listened hard with the window open, I was told to put mobil 1 trans fluid in and that may have helped.

The extra clutch grab alone will make a noticeable difference in acceleration (that clutch grabs HARD), plus you lose less horsepower to the rear wheels because you are eliminating at least 20 lbs of spinning weight. And you will notice a difference with the quicker revs. If I had a 528 and my clutch was worn that would be my first mod, very happy with it on my 328.

Dude Dan doesnt have the UUC flywheel. Its a JB Racing Flywheel which isnt as loud. Any which way you slice it, light flywheels will rattle a bit. The Jb racing wheel looked really highspeed. Well built and didnt look like it belonged on an accord (R-type :rolleyes)

Good luck with that one. If it gets too loud, you can always yank it out and put it up on the wall and take alot of cool pics along with that piggybank :D


If im jealous, its because I have an auto. Not because of that aqua colored flywheel :)

My reference to Dan was just related to the company, not the product.

Piggybank FTW.

A JB flywheel is lighter than a UUC flywheel. So if transmission rattle is caused by a lt flywheel it should be worse with a JB than a UUC.

Also hope you don't get banned for giving a negative opinion about it on here. Poor Dan.

"Poor Dan" was banned for bashing multiple vendors in general, and several individuals in particular despite repeated warnings. A real shame to see a smart guy behave so badly.

Precisely. That's plain common sense.

As I've said (and proven) countless times, individual cars respond differently depending on each examples wear characteristics, build tolerances, fluid condition and type, and other variables. To compare Joe's car with Brand X to Tom's car with Brand Y and make a conclusion is foolish. The only valid comparison is in the exact same car.

All other factors being equal, we believe the UUC flywheels are tuned to an optimized balance of performance and minimal gearbox rattle. That we sell literally thousands of flywheels per year and just a few people have sny sound at all is worth noting. The problem is, of course, that just the few people complain and the majority with quiet flywheels are too busy driving their cars and smiling to post much! :D

Yeah... I hate this crap. Then again, it's a free forum supported by vendors such as UUC. What else should we expect I suppose.

It doesn't just happen on this forum - it's pretty common.

I'm not going to say who was right or wrong since I wasn't a party to the carnage. It was just a tongue-in-cheek comment.

Yeah... I hate this crap.

Seriously, if you really do "hate this crap" then don't perpetuate it - especially if you do not know what happened. Also, it would really be appreciated if it was not incorrectly perpetuated that a vendor got a poster banned. If a person can't control themselves, then this mature forum is no place for them and the moderators take care of that all by themselves.

Nobody, vendors or private people, should be expected to put up with harassment and false accusations.

Want to know why some forums die, why knowledgable people and vendors stop posting? Trolls. People that do the sort of things that, luckily for us, the Bf.c moderators watch for and remove the offending individuals.

But a Vendor DID get Dan banned. Its a FACT. So please don't try to butter up the situation. This thread should be closed since too much truth and fact is in it.

I do understand and respect that this forum is most Vendors Lively hood. So when someone does come around to spew fire about them, they will be taking a defensive stance. Maybe even go "running" to the higher ups to get someone banned because they didn't like the way a certain person made their coffee taste in the morning.

Also BFC mods cant see everything. Its the little babies that bring them the dirty diapers.

I would bet that whatever you think you know of the situation is wrong, especially if you've heard it from Dan.

Did several vendors complain? Oh, definitely. Did several individuals complain? Absolutely. Did a mountain of protests against him cause the ban? Yep.

So, if you want to "butter it up", it's that the moderators gave him way too much leeway and way too many warnings before pulling the trigger.


I do understand and respect that this forum is most Vendors Lively hood. So when someone does come around to spew fire about them, they will be taking a defensive stance.

I realized what you're missing - you're defending Dan about something that never happened.

Dan never posted "I had trouble with Company X, this is my experience." No... Dan posted, "I don't like Person Z, therefore I am going to make things up, twist around things I heard, and push questionable and often non-existant product that is sold by friends of mine or just anyone else."

So if "spewing fire" means one can comfortably swap "fire" with "total b*llshit", then you're right.

Also BFC mods cant see everything. Its the little babies that bring them the dirty diapers.

Rob, you are getting way too defensive about a joke. If you're a business man with hopes of growing said business, I'd just leave it alone and brush it off as yet another chop-busting comment on bf.c. Arguing and fighting makes you look bad in many people's eyes - unprofessional even. Some that had no obvious opinions of UUC are probably starting to develop some as a result.

I'm with Gumbi - just close this thread Mark/Jamie. It's usefulness has been exhausted.

Finally, I'm one of those guys that spends several thousand dollars a year (above maintenance) on my car. I almost always use forum vendors so that I can do my part to keep this place moving. I don't need to be attacked by one.

I'm out.

I'm talking about an E39 540 here.

Bimmerworld has complete ltwt flywheel and clutch packages. I researched UUC, JB Racing and others and decided that when my clutch goes (maybe soon) I will go with Bimmerworld, in part because their flywheel is a little lighter at 14 lbs than UUCs.

I think UUCs flywheel is 22 lbs, Rob please correct me if I'm wrong.

JBR also makes a racing flywheel for the 540 at 8.5 lbs. That is way too low for street only use.

Please lets jsut be friends!

My apologies. I don't think the 'NJ crew' was necessarily defending Dan though.

We now return you to your regularly scheduled thread. Good luck James! Keep the pics coming. They're like food for the natives.

I don't know but I would sure find out before I took it apart.

I'm not so sure it would work, the clutch disck and the pressure plate bolt holes have to line up with the flywheel's working surface and the holes in the flywheel.

UUC is 16.6lbs.

We've come to this weight as the ideal balance between increased performance and low likelihood of gearbox rattle. 2.6lbs won't increase performance appreciably but will increase gearbox rattle.

- Rob

thing is my clutch is farely new... i think 6k miles on it. i'm assuming a ltw fw will work on a stock clutch

It will, assuming the flywheel is made to use an OE 540i flywheel. The UUC OE-size clutch flywheel would work.

BUT...

1) The OE clutch does not have a sprung-hub center. This means that there is no internal damping against gearbox rattle... so combining a solid lightweight flywheel with a solid-hub clutch kit pretty much guarantees you will have noticeable gearbox rattle.

2) The OE clutch is the SAC (Self-Adjusting Clutch) design which requires very special tools to install and re-install. BMW dealers often get this wrong, and I have yet to meet an independent who has the re-install tools. This procedure should scare you (download free viewer from www.efax.com):
http://www.uucmotorwerks.com/images/SAC_CLUTCH_INSTALL.efx

3) The OE clutch is the primary problem that most people experience in the first place - E39s simply chew through clutches. Re-installing one that is 10%-30% worn out already may be "false economy" as a clutch job usually costs $600-$1200 (depending on Independent or BMW service), which you would have to pay again all the sooner with a prematurely failed/worn-out clutch.

Food for thought?

UUC is 16.6lbs.

Rob. I lifted the below from that other forum, the fest, where we talked about weights. If I have it right you were saying the UUC is 13.5 lbs lighter than stock. And stock is 40 lbs I think. That makes the UUC unit come in around 26.5 lbs and not 16.6 lbs.

Would you please shed some light on this? Thanks. Frank

I'm going to have to double-check original weights as I might have been cross-mixing some info with the M5 parts.

Nevertheless, the 16.6lbs is accurate... I put one on a scale right before I made the post. :D

Ok

To be sure we are all talking of the same thing... are we talking about the flywheel weight alone or with the clutch disk and the pressure plate included?

The 40 lb figure for a stock 540. Is that flywheel alone or the flywheel, disk and pplate?

Ok

Flywheel weight alone.

Pressure plate and clutch disk are relatively the same regardless of brand, aftermarket or OE.

That number should have been for the flywheel alone.

Four day count down until the flywheel.


I jsut need to go to the Stealership and buy flywheel bolts as i dont want to get stopped because i strip one (happend in Pelican Parts' DIY).

http://i88.photobucket.com/albums/k197/ivdogz/CIMG1019.jpg

Something big time is wrong if you are stripping the bolts.

Rob,

I know we discussed this above but for an E39, 540 your web site states a 13.5 lb weight 'savings' over the OEM clutch. OEM clutch is 40 lbs.

So 40.0 - 13.5 = 26.5 lbs flywheel wt

So according to your web site the UUC flywheel is 26.5 lbs.

But above you stated its 16.6 lbs

Either your web site is wrong or your flywheel weighs 26.5 lbs and not 16.6 lbs

I'm not doing a gottcha. I want to know what it really weighs because a LWF is in my near future, and I want to know ahead of time which to buy when that day comes.

Additionally it would be helpful if your web site stated the actual weight of the flywheel. It does not now, it only states a weight savings or reduction.

From Pelican parts:

The link to the DIY

http://www.pelicanparts.com/bmw/techarticles/E36-Clutch_Replace/E36-Clutch_Replace.htm

Rogue and Bimmerworld both use JB Racing flywheels.

Rogue shows a weight savings of 22.5 lbs versus UUC's weight savings of 13.5 lbs. Again this is for an E39 540.

If you are talking about damaging one or more while removing the bolts, well that shouldn't matter as all new bolts should be used for the install.

Cutting the head of a bolt off with a grinder still leaves the thread of the bolt in place and still a problem to deal with.

The OEM clutch (Sachs) is self adjusting.

Aftermarket clutches are not self adjusting.

My question then is how does one adjust an aftermarket clutch for wear?

You don't.

You've never had to.

The whole SAC thing is a unnecessary over-complication that sacrifices reliability for only one "feature"... whereas in a normal clutch, as the clutch wears, the engagement position moves slightly. Most people do not even notice. The SAC eliminates that movement - so all that effort, all that complication, all that decreaesed power capacity, all that sacrificed reliability - all so the pedal position upon engagement doesn't move by 1/4" over the lifespan of the clutch. A pointless exercise. SAC is evil.

I've had Chevy clutches, with a sprung disk like yours and other aftermarket units, that do need to be adjusted as they wear down.

I completely missed this post 30 days ago, sorry for the delay in replying.

The reason the website states the reduction in reduced mass is because the pressure plate weight is also a factor... it's rigidly bolted to the flywheel. The V12 pressure plate is substantially larger and heavier than the E39 pressure plate. Will try to take pics with exact weights shortly for you.

I've had Chevy clutches, with a sprung disk like yours and other aftermarket units, that do need to be adjusted as they wear down.

We're talking BMW clutches here. No BMW clutch has ever needed adjustment, it's a different type of system.

Other-brand cars that require clutch adjustment need that because of other factors; usually, it's a cable-actuated clutch and the cable stretches with time. It's not the clutch disk wearing that causes it, it's the cable! Just like the cable-actuated brakes you had on your Schwinn 10-speed as a kid, where cable adjustment was part of the service procedure. Other types of cars with hydraulic systems that need adjustement have, for some reason, master cylinders that go out of spec. BMW master cylinders don't do that... they just fail. :D

The clutches I changed and adjusted had a solid rod adjuster against the throw out bearing lever arm. One end was threaded inside the other end and by turning either you could change lgth and then lock it down with a nut.

Yes... and no BMW has ever had that, or needed it.

There's nothing special about the E39 transmission compared to earlier BMWs. In fact, with the exception of the timing sensor port, it's the exact same transmission as used in earlier BMWs that used a conventional non-SAC clutch.
