I have been doing some more research on using the M3 Clutch and Flywheel in our cars and have found some interesting information. I talked to the guy over at Understeer and he said that the M3 Aluminum Flywheel and Clutch fits right into e36's with the M42 and M44. He did not know if it would work or not on the e30 M42 because of different trannys.

I then proceded to check a few things. I know that people said that the getrag 240 tranny can be used when swapping s50's into e30's. Therefore we know that the bellhousing on our getrag 240 has the same bolt patern, and dimentions as the e36 M3.

One thing I know for sure is the e30 m42 tranny is different then the e36 m42 /m44 tranny (from the outside, just looking at them)

Second thing I checked was the flywheel and clutch kit for the e36 318is and 318ti and guess what, its the same exact part numbers as the flywheel and clutch kit for our e30 m42 engine/getrag 240

The third thing I checked was to make sure the pinion gears on the starters between the e30 m42, the e36 m42/m44 and the e36 m3 were the same. And they were.

So... since everything is the same it should work right? We should technically be able to put say a 95 m3 clutch and flywheel into our cars.

Are their any variables im missing?

is a 95 m3 clutch and flywheel cheaper or something?

also is it year specific for the M3 parts?

zerofreez · « **Reply #32 on:** June 08, 2006, 07:58:22 PM »

Its not really cheaper, just has more surface area and allows you to (if you get the sachs heavy duty clutch) have a sprung hub clutch disc

M3 clutch can hold 350 ft-lbs of torque, and would also last much longer.

I just think your getting more for your money if the m3 clutch/flywheel works out.

Damn I would just like to see a s50 that someone has laying in their garage, with a clutch/flywheel on it. I have a getrag 240 sitting in my living room, that would answer some questions really quick.

I dont believe its year specific. You just have to make sure your flywheel is ment for your clutch. (example, you cant use a 95 s50 m3 flywheel and a 98 s52 m3 clutch kit)

clutch cilinder is different, you should use E36, o lenghten E30 rod (cut apart and weld inside bolt) about 4cm but better way is to make it adjustable because 1 mm make huge difference. Also bearing No5 which is fitted in crankshaft has different inner diameter, it depends on production year.

And you should cut one peace from gearbox, which will not let you to fit lambda sensor.

If im using the same tranny just a different clutch and flywheel why would I need to worry about the pilot bearing or clearance with the oxygen "lambda" sensor?

Have you done this before?

i think we need a group buy in a few months..

his sig says "close ratio gearbox" he must have a Z3 or e36 318 box.

so here is jb racing's e30 m42 flywheel compaired to a 95-99 m3 flywheel.

Looks like it will work, the size rating is for clutch diameter and not flywheel diameter so it looks like it would work.

I'll take more clutch surface area and 80 bucks cheaper

I have the BMP 9 pounder, and driving in traffic is no problem other than not being able to go anywhere. To me, the chatter is very minimal and I hardly hear it with the stereo on, and I don't have the volumn up very much. As for stalling, that hasn't happened to me yet! This is by far the best mod I did for this car. If it's a matter of a chip or FW, I would go with the FW and get the chip later. Driveability is not affected IMO, and I've had it in my car since Feb of this year. However, the FW is made for the M42 and the OEM clutch, so I don't know what problems other versions will manifest.

Since I had the FW, I was able to take my class at autox rather easily, and I also had a 1 sec quicker time over an M3 during track day. The car spools up very quickly, and you can actually feel the pull. My only regret is I waited too long to do this, and our track has been closed since April!

so i need a new clutch fairly soon, and money is a big deal since i am saving for IE3s/Bilsteins and some rubber. What would be the best combo for price and performance? i dont need ULTRA light but i def. want an improvement over stock.

Good Morning Everyone,

I hear a lot of good things about going with the LWFW. However, uncertain future plans with my M42 have put my project on hold, mainly because I don�t know what I will be doing with her (engine performance).

My plan is to keep the 318 for a long time. So my question for the forum is how adaptable is the LWFW with the following performance choices:

1) Stock (maybe a chip!) � I guess this has already been answered. Seems like it�s a 100% improvement.

2) M42 dream engine ala Febi Guibo � will the aluminum 9lb LWFW work with this engine?

3) M42 DASC � same question as above � will it work?

4) M42 Turbo � same as above

5) S50/S52 � besides being banned from the forum, will the FW fit?

Thank you,
Chris

any updates on the m3 clutch?

zerofreez · « **Reply #44 on:** July 11, 2006, 06:25:56 PM »

No. I wish I had some money to figure it out. I suppose I could try and see if the parts dept will order me a e36 m3 flywheel so just so I can look at it. But then again I dont even have a m42 flywheel to compare it to unless I take mine out.
