View Full Version : Stock M3 Flywheel in a ti????
I doubt this has been done, but I was wondering if it is possible to fit the stock M3 clutch and flywheel into a ti. I need a new clutch, but I can't afford to go with a lightweight flywheel right now but I can get a really good deal on the stock M3 setup and just wanted to verify that it would work. Thanks.

Im replacing my clutch this saturday with the Sachs clutch kit from Bavarian Autosport.
I wanted to put a lightweight Flywheel in mine too but figured that its not really needed since my ti is an everyday driver. Im going to use the original flywheel with the new kit.
Im not sure if you can use the M3 flywheel on the ti. I'd be interested to find that out too.
I dont' see any reason that it wouldn't work, but you never know with bimmers.
I don't see any advantage to using the M3 flywheel. I expect it is at least as heavy as the stock ti wheel, if not more so.
The M3 clutch and pressure plate may be worth using, and I'm going to go out on a limb here and say it will bolt to the ti flywheel. The flywheel size is the same, so it follows that the bolt pattern for the pressure plate will be the same.
I have not tried it, so I may be wrong, but I'm guessing it will work.
Since the ti clutch never slipped on me, unless you are running boost or some other 'hop-up' I would not expect to need a different clutch from stock...
i'm just looking into this since I can get it cheaper than a new ti clutch (it's used with ~2500 miles)

It has been done MANY, MANY times. It is also slightly lighter than the stock dual-mass ti's flywheel.

PS I have a lightened M3 flywheel in mine.

The stock M3 flywheel (at least off my '96) weighed 28 lbs. I would say definitely do not use this flywheel unless you have no other choice. I don't know what the ti's weighs, but 28 lbs seems awfully heavy to me.

M3's stock flywheel is about 3-4 pounds lighter than the M44 one. However, the extra weight from the M3 clutch disk/pressure plate make the total weights of both clutch systems about the same.

I have an M3 flywheel available, if anyone wants it. It's of a '99. I used an aluminum one when I did my swap.

Wow, we have heavy stock flywheels...

Why don't you just use the original flywheel? Thats what I'm doing when I install my new clutch this weekend. You'll save some loot doing it that way.
Unless you think your original flywheel is ruined.

The original flywheel is probably fine, but this is going to be about $5 cheaper after everything that just getting a new clutch kit. Plus I get a stronger clutch and a clutch that just may have some feel to it. Anyways, thanks guys. I'm going to go ahead and buy the clutch and flywheel and hopefully it will work (again, I see no reason that it wouldn't but now I can blame you guys if it doesn't :mrhappy: )

My favorite mod by FAR! is the lightweight flywheel and the kevlar composite turbo clutch.
I have done the SAME mod to my 2 M3's and now my **** basket Ti which i love!.
Flywheel makes your car more responsive ans snappy! hit the gas and the RPM's are there NOW. BAAAM!
Disadvantages: Clack clack noise @ idle.. gets worse when hot and AC on... If you install a FW, you cannot have Pulleys or underdrive the Harmonic Balancer.
Recomended to Balance the Clutch plate to the Flywheel and disc.
Heavy clutches will be a pain in the ass in traffic, if you track your car, flywheel is a great thing to have, will make your car develop the RMS's quicker.
People will say" Dam, your car is Kknocking BAD! sounds like poop!... you say: "yeah I know.... wanna race?? $50?? " they ALWAYS buy it. I found that TC Klein flywheels have the LEAST knocking... and if you wonder where the sound is coming from???
THE TRANSMISSION... OEM FW are Dual mass.. rubber dampens the noise... Aluminium is single mass.
If you are using the M3 pressure plate, you will want to replace the slave cylinder with the M3 piece as well.
This is unless you want your left leg to be larger than your right leg...
I did this when I did my swap, and there is plenty of 'feel' there.
Not being able to hold the clutch down does not make you more of a man.

I was driving my car the other day and my cousin who is a licensed 1/4 mile race driver told me that when racing a stick you basic rev high, dump clutch and keep your foot in the gas as you **** gears.. i tried this on the street the other day and car left great... but when shifting... the needle took forever to drop... is that simply the clutch not being able to grab on while its spinning so fast? would a stronger clutch help or were these cars simply not meant to even try this?
What would fix this.... i noticed that dropping off the gas and press again fixes this. Any ideas or advice to stepping up?

That sounds like your clutch is going out. If you are modded, or plan on doing any major power adding mods then I would go with the M3 clutch/flywheel combo since it can take the extra torque alot better than the stock ti clutch can.
Secondly, your cousin does not know how to launch on street tires, that or he just didn't tell you how. You want to slip the clutch, tire spin is not a good thing when launching.
Here (http://bimmerforums.com/forum/showthread.php?t=47538) is a good read on how to launch on street tires.

Yeah, basic idea is i was in a factory district and this guy with a cadillac CTS pulled up next to me. I basically asked my cousin why it was i kept falling behind at every shift and he laughed... (i just learnt how to drive stick recently)... he said... ummm.... 1 you need to shift faster and two... did you let off the gas when shifting.. i said.. YEAH... arent you supposed to??? he said sure if you're driving to work.. but not when racing.. i asked you supposed to keep the gas in... he just said yeah... i figured that's what he meant?!?! go figure.
