Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

WOOT! UPS came and left not 5 minutes ago... Great deal at $800 shipped ($750+$50 for 3 day UPS) from Ultrarev.com. Ordered Monday afternoon, in my hands on Wednesday. Pcar is up on stands waiting on the clutch kit to arrive from Suncoast. Install on Friday and off we go! This is why I prefer to do any of the maintenance myself that I can. Figure around $600 or so labor for clutch replaced at the dealer which is not much less than the flywheel. Win-win.. Yes, I have heard about the chatter, etc. have driven cars with LWFW's before (last was a '90 300ZX Twin Turbo with a twin plate clutch and Unorthodox LWFW. It was dyno'd at just shy of 425 RWHP and while there was some chatter it was not unbearable by any means). Basically it is a trade off.

POST 3Original post

As long as the ECU can keep up with it? Have one on my 964 and love it but the car does stall every once in a while. Will also take stress off of the rear main seal, so might help avoid a leak??

POST 4Original post

Quotes source post: 4733369

Not sure about that... it does chatter, more vibration.

POST 5Original post

Can these single mass flywheels be resurfaced?

POST 6Original post

Quotes source post: 4733369

no need to do anything with the ecu. mine has been fine since day one. i think you are right about the LWF relieving stress on the RMS. mine has not leaked and i have 99K miles on it.

POST 7Original post

Quotes source post: 4733641

the aasco unit has a friction surface that can be replaced.

POST 8Original post

Hmm, so that's what it looks like. You probably should have purchased the Plenum

POST 10Original post

Quotes source post: 4733179

You're going with a single-mass LTW flywheel mated with factory clutch kit? Any reason why aside from not wanting your left leg to be larger than the right leg?

POST 11Original post

Quotes source post: 4733928

The only reason to change to a stiffer pressure plate is if he is adding torque...which a lighter flywheel doesn't do?

POST 12Original post

Quotes source post: 4734375

The stock clutch hub is rubber. Aftermarket clutch hubs are sprung hubs. I'm curious to see how the aftermarket single mass LTW flywheel works with the stock clutch (rubber hub) and PP.

POST 13 / ORIGINAL POSTEROriginal post

The clutch kit is this one: http://e-partssales.com/Merchant2/me...y_Code=996main The box the LWFW came has a label which says: "CAN BE USED WITH A SPRUNG CLUTCH DISC" I spoke to AASCO and was told that they had modified the design from the original and that it would work fine with the OEM clutch. I was told this as well by Suncoast. Hope all goes well, will post pics of the OEM clutch with the LWFW as soon as the clutch arrives on Friday. <FINGERS CROSSED all goes well and play nicely together> EDIT: Wanted to show the clutch so all can see it is sprung.

POST 14Original post

Yeah! It is a sprung hub. HMM. I'm curious to see what your impressions are with AASCO and stock clutch.

POST 15Original post

Any idea what the weight savings is? Actual vs. advertised?

POST 16Original post

Ultrarev is a great place to buy parts for a great price. I've been emailing them and they keep stating a Findaza flywheel is available for our 996 N/A application also.

POST 17Original post

Quotes source post: 4734984

BTW - it is Fidanza, not Fi n daza. I am not sure that is true. If you do a search on "Fidanza" you will find that a few other guys ordered a Fidanza FW and found that it had the wrong number holes for mounting. Maybe they have come out with a new FW for the 996?

POST 18Original post

Quotes source post: 4734984

i got the fidanza LWF from ultrarev and it was wrong.... had 9 bolt holes instead of 8.

POST 19Original post

Quotes source post: 4735063

BTW it is FIDANZA not FIDAZA

POST 20Original post

Quotes source post: 4735242

OOPS! You are correct, I thought I had "moved" the "n"! Original post corrected!

POST 21Original post

Quotes source post: 4734512

Are you sure that is just not some generic stock photo? I'm pretty sure the 996 stock clutch is "solid". That's why the dual-mass.

POST 22Original post

Quotes source post: 4734512

I purchase my clutch kit from Ebay for about $100 less. My clutch kit is a bit different though. http://cgi.ebay.com/ebaymotors/Porsc...ayphotohosting

POST 23 / ORIGINAL POSTEROriginal post

Quotes source post: 4735789

$100 less? More like $70 (ebay is $358, OEM from Suncoast is $430). For $70 felt better about Suncoast... To answer another post about weight; do not have the original flywheel off yet so cannot weight it but FWIU they are around 35 pounds. The AASCO is 13 pounds. Quality looks to be excellent.

POST 25 / ORIGINAL POSTEROriginal post

Quotes source post: 4736622

Yes, 1990 300ZX Twin Turbo... Miss it in some ways, not in others. Here is a pic of it before I sold it It was very fast (just under 425 RWHP) but the Z's have a severe traction issue due to no rear end weight. My 996 may not have the HP it had but: - Ride in the 996 is MUCH better (though on the Z it was much my fault due to replacing every rubber and silicone filled bushing <including those in the rear subrame> with urethane ones. Would definitely rattle your bones in the passenger seat!) - Better traction in the 996 - MUCH better retained value in the 996 - It is a PORSCHE! 'nuff said!

POST 26Original post

Quotes source post: 4736319

Actually, my purchase price shipped was $100 less than what you paid, I was just showing the picture of what I bought. I'm Glad you feel good though.

POST 27 / ORIGINAL POSTEROriginal post

Quotes source post: 4737116

Ah.. I figured you paid what the ebay listing showed.. You did indeed get a good deal then. I spoke and emailed with that seller but got cold feet based on his knowledge and such. Good to hear all worked out!

POST 28Original post

Quotes source post: 4737185

Understandable, I rarely deal with Ebay but the model number he had matched the model number I saw on popular web sites.. What I really wanted you to notice was that the friction surface on mine is slightly different than yours. Did you notice that?

POST 29 / ORIGINAL POSTEROriginal post

Quotes source post: 4737336

Will let you know tomorrow when the clutch arrives...

POST 30Original post

Quotes source post: 4735063

Yeah yeah. Didn't have my morning coffee. Anyways I had a Fidanza LWFW in one of my other cars before no chatter. The saleperson there did tell me what they sell is the 8 bolt version.

POST 31Original post

Quotes source post: 4738650

That's OK, I screwed up the spelling on my "correction" because I left the "n" out completely. Unfortunately, I did have my morning coffee prior to that.

POST 32Original post

Quotes source post: 4737336

The eBay picture looks correct to me from other posts I've seen. (Not a sprung hub.)

POST 33 / ORIGINAL POSTEROriginal post

A couple folks thought there might be an issue with the friction area on the AASCO flywheel not mating up with the OEM clutch disc. Got the transmission pulled this morning and took a couple pics. Laid the used clutch disc on the AASCO flywheel and the friction areas mate up perfectly! Here is the old clutch. Good, NO GREAT TIMING!, the wear had just barely started to touch the rivets! YIKES! All I am waiting on now is for UPS to deliver the new clutch kit so I can put it all back together. Total time spent to this point is 4 hours BUT that includes a few phone calls, getting something to eat and dealing with the carpet cleaning guy that came today. Now that I am almost done, what is the recommended break in procedure?

POST 34 / ORIGINAL POSTEROriginal post

Well, almost done. Took a few hours off, all that is left is reconnecting the shift linkages, plugging the reverse light switch back in, torque the half shafts and the underbody plastic pieces. Was actually a pretty easy removal. Reinstall of the transmission was another story! For the life of me I thought I would never get it stabbed back in! Finally remembered a trick; got a few bolts and took the heads off, screwed them in the bell housing bolt holes and used them as guides. Of course would have been a breeze if I had a lift. Doing it on jack stands was a PITA! Will post impression tomorrow after a drive, of course will not be able to offer much since it will be a day or so before break in of the new clutch is done.... Thanks to one and all for the help!

POST 36Original post

Quotes source post: 4733179

How many AA batteries does it take?? I bet I have to change mine.

POST 37 / ORIGINAL POSTEROriginal post

Quotes source post: 4884156

Have ~450 miles on it and I would definitely do it again. Good bang for the buck and especially if you need to change the flywheel anyway (mine was still in good shape) it is a no-brainer riad... those are the old dead AA's from the old FW. New one runs off dilythium crystals...

POST 38Original post

Quotes source post: 4884959

Thanks. I may need to replace my clutch soon (slipping a little in 1st gear only) and I may go ahead and upgrade the flywheel as well. Do you happen to have the part numbers of the parts you ordered from UltraRev and Suncoast?

POST 39 / ORIGINAL POSTEROriginal post

No part numbers, just called them up and told them I needed a clutch kit. They sent all the necessary parts required. If you get the AASCO LWFW it includes new flywheel bolts. For the LWFW Part# 106411-11 Porshe 996 I paid $750 for the LWFW
