I've also fitted M3 240mm lightened flywheel with clutch kit on my M44 with no issues as plan was to fit the DASC till I found out it no longer exists...orz.
was thinking of going for the mid sized 228mm but could not find any lightened flywheels.
some say its better to put a spring loaded disc from the 5 series or M5, I forgot, for better engagement.
I had no issues with engagements so kept using the solid disc type, its been 6 years now without any issues just the chattering noise.
initially I used the M3 slave cylinder but changed to the ti/is slave cylinder for shorter pedal stroke but it sure made it heavy feel...
Here are some of rough numbers I know....may not be correct
M3 original flywheel: 26.5lbs
lightened flywheel: 16lbs
cover: about 12lbs
disc: 2.2 to 2.6lbs
M44 original flywheel: 26.9lbs __________________ taishi |
