Replacing Dual Mass Flywheel - balancing?

[grahambehan]

First, yes if you buy a Stock dmfw that has been used. If you find NOS, there will be no weights added. Second for the 93 design we were looking to reduce reciprocating mass, the rods were lightened by extra machine work, which reduced the variation from the previously " as forged" areas.

I find this very interesting. I will have to check the original dual mass flywheel/clutch/ pressure plate that I have on the shelf to see what configuration it was from the factory. I removed it from my '91 LT5 when I switched to an automatic trans.
