But I guess it would apply for the E36 M42 flywheel conversion too... and FYI, the 325i flywheel mentioned in the article is the E30 M20 325i flywheel, not the E36 M50 325i flywheel. Not sure which flywheel is your M42 running on but it's most probably the dual mass flywheel. bear in mind that the heavier flywheel was to help with your low to mid range torque. I don't think there's anything u can do with the dual mass flywheel. U can choose to change the flywheel to a single mass M40 flywheel. I have weighed it at about 10kg (~22lbs). I have also lightened the M40 flywheel to 7.6kg (~17lbs). u might have the change the clutch set to the M40 clutch set to go along with the M40 flywheel. Better to check with ETK for confirmation.Acceleration with the lightened 7.6kg flywheel was much better compared to the 10kg stock flywheel. Slight loss of low end torque but there's no best of both worlds, so it's a compromise I can leave with. Then again, my ride is an E30, not the heavier E36. Note: Bear in mind that the weight of the clutch sets were not taken into account. The different clutch sets may have different weight.ps: I have the stock M40 flywheel sitting pretty at home...</blockquote>
