A stock single mass e30 flywheel came in two forms i think. There was an early model that had a different weight. Most standard 325i flywheels were 18lbs.
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 r3vlimited.com, 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.
