We have dual mass flywheels. Single mass fylwheels are in the e30s. Dual mass flywheels help to keep the driving feel "civilized" and comfortable rather than sport like. There is a lot more weight on them to keep the revs from dropping so quickly and making shift points smoother and not so jerky compared to a lightweight flywheel. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Is yours messed up or something? If i were you and needed to replace the flywheel, id go with a lightweight one, nothing extreme, but something a little lighter than the stock 28lb one. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Ah, i see. No, there isnt a choice, dual mass all the way. Are you getting a stock clutch setup? __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

I would not buy a dual mass flywheel as a replacement. They are outrageously expensive ~$900. Just get a single mass and it will be cheaper and work well. I would not get a very lightweight version. But something in the 15-20lb range?
You can also swap a M20 single mass flywheel in, but you have to change the pinion on your starter, too. | | | | | 10-13-2007, 12:23 AM | #10 | | Senior Member Join Date: Nov 2004 Location: Minneapolis Posts: 1,587 |
There is actually a choice when it comes to stock 318ti flywheels and clutches. If you look in the ETK ( www.realoem.com) the european M42 318ti had a single mass flywheel and a dual mass flywheel. I assume the difference was AC vs. no AC. I think all American cars had AC, thus only dual mass flywheels. Sorry for the shamless plug,  but I have one I've been trying to sell for a while. http://318ti.org/forum/showthread.php?t=11586 | | | | | 10-13-2007, 12:51 AM | #11 | | Senior Member Join Date: Jan 2004 Location: Northern Michigan Posts: 867 |

I just installed an Aluminum flywheel (13lbs) and M3 clutch and I can't notice any difference vibration wise, even with the air on. I also didn't notice any drivability difference, besides it being just slightly easier to stall from a stop, it still shifts very smoothly. It now revs much quicker in 1st and 2nd and doesn't slip! __________________
