I HIGHLY reccomend the Metric Mechanic 10.9 lb single mass flywheel and 228 HD sprung clutch option for these cars.

It's a bolt in option and no need to mess with starter gears or spacing rings. It's a no brainer.

It's great!!!!

The following quote is from an email I received from MM about LFW:

Hi Chris,
The lightened flywheel for your car is a great performance modification. Unfortunately the flywheel in your car is a dual mass flywheel, which can not be lightened. What we sell is a E30 325is flywheel. This flywheel weighs about 20-23 lbs from the factory. Our lightened flywheel weighs about 10-12 lbs. With our flywheel you also need a clutch & pressure plate kit to go along with the flywheel. This setup is a perfect plug and play kit with no other modification needed. In the end you will get rid of the dual mass 28 lb flywheel for a lightened single mass flywheel. The kit sells for $700 and includes the flywheel, a 228mm clutch disc, 325 pressure plate & release bearing. We would need your ring gear from your flywheel or if you don't want your car down that long, we could send you the flywheel first and charge you a $100 core deposit until we receive your ring gear from you, at which time we refund your core deposit (assuming it is a useable core). If we can help you, give us a call at 573-765-1269.
Thanks!
Regards,
Court

A lightweight flywheel from bmp is more cost effective...a 9lb flywheel for $500 is a plug and play install as well. While this is a 10-12lb flywheel for $200 more.

i dont see the point in going that route.

the problem with the aluminium flywheel is durability... when I was out at MM (court is THE MAN btw) they had a bunch of relatively low mileage aluminium flywheels lying around (around 20k mi) that looked like ass... pitted to hell, worn teeth, etc. They were pulled from customer's cars and replaced with a setup similar to what shellback is describing. Doc Sheepdog can verify what I'm talking about.

I have the MM lightened / resurfaced steel flywheel and it's half the weight of stock and totally driveable in NYC traffic (eg, when I'm stuck on the Belt Parkway driving to denis' place!!)

also, note that the $700 MM price includes a new sachs sport clutch and throwout bearing.

how bad can it be?? i mean im not gonna be separating the tranny and the motor just to take a look at how the flywheel is doing. It doesn't really matter to me how it looks..as long as its doing what it has to do then thats fine with me. however, the worn teeth is a concern for me, i wouldn't want the flywheel to be skipping a beat.

Febi makes a valid point that should be considered. Jim at Metric Mechanic was explaining to me that aluminum is great for racing applications, but not preferable for daily abuse...

And just my $0.02 worth... daily stop and go traffic is actually more abusive on a clutch/flywheel than racing, where it's in-and-out. Riding the clutch in stop and go Atlanta traffic is WAY more abusive! The metalergy of the stock flywheel is built to withstand they day in and day out abuses and reliability of a production car used in all sorts of situations and climates.

I can vouch for what Febi says... the Metric Mechnic solution doesn't present any drivability issues and idles like a fine swiss watch! I'm very pleased with the solution.

I'm not saying the aluminum option is bad.. But, I can't reccomend it and personally wouldn't go that route myself.

Now if we could only lower that price on the MM flywheel kit it would be a no brainer. Did somebody say groupbuy?

so is MM using the 325 TOB? thats what it looks like in that email.

Yes. Actually, the price isn't too bad considering the cost of the flywheel and the Sport clutch together is almost the cost of the JB aluminum flywheel alone.

But, I'd call Metric Mechanic and see if they will do a group buy. If I were a bettin' man, I'd guess they would. :cool:

this is from someone who was trying an s50 swap on their 318

Ok fellas the e36 M3 Pressure Plate wont fit inside the getrag 240 so i ended up going with the 318is clutch and pressure plate for now its brand new ,i am wondering how long it will last.

Fife318is · « **Reply #55 on:** July 23, 2006, 09:18:51 PM »

Wow, this sounds like an awesome mod. Dont know if Id like the chatter aspect of it though. When it comes time to do a clutch I think Im just going to go the m20 flywheel route.

M42boy · « **Reply #56 on:** July 23, 2006, 10:38:24 PM »

Okay, here's some pics of the Metric Mechanic lightened single mass flywheel and 228mm Sachs Sport clutch kit I installed.

It weighs in a 10.9 lbs and has no drivability issues. Much better response.

dude8383 · « **Reply #57 on:** July 25, 2006, 07:02:27 PM »

ok to clear things up with the 95 M3 flywheel...

in order to have this flywheel in our transmission, it must be paired up with a 240mm clutch. Correct?

nickmpower · « **Reply #58 on:** July 25, 2006, 07:30:00 PM »

it wont work
