Lightening it by shaving some medal off could bring you down to 13-15lb conservatively, or 11lbs if you get aggressive.

Do a search on, you'll find alot of info there or start another thread. I might actually have one for sale, have to check my storage to see what left over e30 parts i still have.
Thanks for the heads up, let me know when you check, I've been doing some research and i've read that the m20 flywheel can be fitted to a m42, with some work. I did read that it was about 18lbs-21lbs but wanted to confirm that! Thats a significant difference over stock which i read was 28lbs+ Apparently it doesn't affect the harmonic balancer at all, so no premature engine wear.
