I think I have the same flywheel (if that's an actual BMW part). You might have some flywheel chatter at idle, but that happens with all but the really expensive flywheel/clutch combinations. For reference, anything that works on an m42 (e30 or e36) will fit on an m44. __________________ '99 Dinan M3 | | | 05-15-2006, 12:18 AM | #3 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | thanks for answer dusten; i think that my ebay link not is an original bmw part, but aftermarket part of M&S (or M+S) motorsport do you have a 15.1 lb flywheel???? with air conditioner ignited, do you have any problem of instability of rpm??? thanks. __________________ I'am italian! | | | 05-15-2006, 12:57 AM | #4 | doesn't care about you.

It's a euro-only part, off of the 318s without air conditioning. RPM's don't fluctuation at all, even with AC on. __________________ '99 Dinan M3 | | | 05-15-2006, 11:49 AM | #5 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | hello dusten, thanks a lot for answer and very compliments for your ti! do you have a E30 318i (M40 engine) flywheel??? the weight of this flywheel is: 9.4 kg, about 20.6 lb while the flywheel that I have find is only 15.1 lb......! __________________ I'am italian! | | | 05-15-2006, 05:23 PM | #6 | doesn't care about you.

That's 7-8 lbs lighter than the stock dual-mass flywheel. Supercharged cars can actually see less performance from a lightweight flywheel, that's why I'm running the 20lb flywheel isn't of a 12 lb, or whatever. __________________ '99 Dinan M3 | | | 05-15-2006, 06:56 PM | #7 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | thanks a lot __________________ I'am italian! | | | 05-15-2006, 08:23 PM | #8 | Senior Member Join Date: Jun 2003 Location: San Jose, CA, USA Posts: 253 | I found an e36M3 light flywheel (11lbs) on sale much cheaper than an aftermarket 318 flywheel. Along with an M3 clutch kit, it worked great, AC was fine as well. And after taking it off 30K miles later, the clutch was still in perfect condition. __________________ Andy Chittum - Mad Man Motorsports | | | 05-15-2006, 09:10 PM | #9 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | 11lb?????? very very lightweight!!! andy, your car is a 318ti M42???? thanks __________________ I'am italian! | | | 05-17-2006, 11:15 PM | #10 | Senior Member Join Date: Jun 2003 Location: San Jose, CA, USA Posts: 253 | It was at that time - as long as you get the appropriate clutch kit, a flywheel from an e36M3 will fit. I think I paid around $400 for the flywheel on sale. Here's more information: http://www.understeer.com/onlinestore-drivetrain.shtml Only difference is that UUC is making their own flywheel now, and they used to sell a remarketed Fidanza flywheel that's a little heavier. Yes, the little M42 doesn't need any extra weight holding it back.
