clutch replacement time, Upgrades?

**jmejiaa** · 09-26-2007, 11:27 PM

I need a new clutch, I can get OEM sachs for 186 bucks and since I only use the car for street I guess this is right. What about my flywheel, keep the one I have or buy a new one? Any upgrades I can do?

**skiboard06** · 09-26-2007, 11:29 PM

how many miles on your OEM dual mass clutch?

**jmejiaa** · 09-26-2007, 11:33 PM

isn't the flywheel the dual mass part? I don't mean to sound like a dick I just want to get my terminology right. Anyway My car car 119k miles and I don't think it was ever changed.

you are correct the flywheel is the DM part. The Sachs is great for street use, there is no need for anything more unless you plan to seriously up your HP. As to your question, I think switching to a single mass flywheel is a good touch. You can typically get a used one for a pretty good deal. You may sacrifice a little smoothness but it will spool much faster and you'll have much better throttle response.

So OEM clutch and a different flywheel? Where do I start looking? What about the UUC and turner flywheels I assume those won't work. I'll start searching but I would appreciate if you pointed some out or gave me some more info.

I love this forum. Every time I learn something new and feel like an e36 genius I have the opportunity to learn some more

How is a different flywheel going to affect my traffic driving? Like bumper to bumper. And by not as smooth what do you mean?

Also my mechanic said something about sending my flywheel to have something done to it I forgot the name but I think it's like shaving a bit off. Is this bad?

**absentmathis** · 09-27-2007, 12:40 AM

As far as I know UUC and Turners kits require a different clutch kit and can get a little pricey. There are other quality makers of lightweight flywheels that can be used with a stock clutch but Im drawing a blank right now. I bet a search can turn up some options. What I was talking about was a stock flywheel from a car like an e30 325, the single mass. They are lighter, again I cant recall the #s(it can be found with a search) and are relatively cheap and will work with a stock clutch setup. As far as the smothness, any lighter flywheel will yeild the same potential problems being minor clutch pedal and drivetrain vibration, easier stalling, and possible clutch chatter. If you have the money UUCs setup is unbeatable though

thats resurfacing, like turning your rotors, and its perfectly fine.

**jmejiaa** · 09-27-2007, 12:54 AM

ok, well It's a street driven car but I have been putting in little things to make it peppier, why not continue right? I have intake, chip, bav auto coils. I know it's like nothing but hey I have to start somewhere. Since I have to do this why not upgrade as long as it's not to expensive.

I guess it boils down to,

1)resurface + OEM sachs clutch kit.

2)single mass flywheel + OEM sacks clutch kit

This is the one I can get for 186

Will this work with a single mass flywheel without noises?

And last, where do I find these? You said used so I assume some e36's have them? Which ones?

**jorbon** · 09-28-2007, 01:36 AM

Lightweight flywheel won't affect your bumper-bumper driving much at all--I doubt you'd even notice it. I put one in a few months back (name of mfgr. starts with a 'z', but I can't remember exactly). Shifts and especially downshifts are cleaner, and there's less rotating mass, so there's more power--may be negligible, but the butt dyno says it might be noticable...

**jmejiaa** · 09-28-2007, 10:12 AM

I think I'm just going to stay oem on this one. Flywheels are like 500 bucks I got better stuff to spend my money on.

for a ltw flywheel and m3 clutch, I have not used one but I hear that they are pretty good and dinan uses them.

**jmejiaa** · 09-28-2007, 10:31 AM

I've heard they can be resurfaced. That looks like a good kit but the added gear noise also scares me. I wish I could hear one and decide.

go to the part that says can I resurface my flywheel and click on the link
I am not try to prove you wrong or argue with you, but trying to help you. Yes you could bring it to the shop and they will resurface it but it will ruin you clutch and flywheel then you are going to have to replace it again in like 500 miles. oem dual mass range from 600-1000 dollars. If you use you flywheel again with out resurfacing it like I did you clutch is going to slip alot and it will eat up your new clutch real quick.
Hope this helps you

**Jeffrie** · 09-28-2007, 12:46 PM

New flywheel is only needed if you drive with a slipping clutch long enough to burn it. My release bearing went on my clutch a few weeks back, once I checked the clutch disk and fly wheel both were perfect and clutch still had more then 60% ware left on it @ 220K on the spedometer. I just put it back in with the new release bering.

It says when doing the clutch for the second time which to my understanding is its good for the life of two clutches... So I guess you must replace it after you go through your second clutch.

**jmejiaa** · 09-29-2007, 01:04 AM

So I don't want to buy a new flywheel, I know that. My clutch isn't slipping it's just making annoying noises. I guess I will take it out and go from there. Thanks for all the help. Another question.... What m3 clutch will fit in my 325i?

**Jeffrie** · 09-29-2007, 01:14 AM

If clutch sounds anything like mine did, it's the release bearing.

**jmejiaa** · 09-29-2007, 01:18 AM

it's not like that, It's more of a chatter. Mechanic said it was the pressure plate.

**jmejiaa** · 09-29-2007, 01:21 AM

Anyone have a clip of the chatter and noise caused by a LTW flywheel? That would help a lot.

**jmejiaa** · 09-30-2007, 01:17 AM

sorry to beat this topic to death but can someone post a vid of the noise caused by a lighter flywheel?

**Black96m3** · 09-30-2007, 01:58 AM

LTW flywheel chatter can get annoying however putting thicker tranny fluid really helps.

OEM dual mass flywheels cannot be resurfaced.

Clutch noise could be pressureplate/throwout bearing.
