aluminum flywheel - ZR-1 Net Registry Forums

I want to install an aluminum flywheel in my 90 but have a concern that hopefully someone can address. The factory dual mass unit come drilled for balance weights on the backside of the flywheel. From what i have seen and read from different suppliers the aluminum units do not. replacement with a factory dual mass unit requires replacing these weights in the exact location as the original flywheel to maintain proper engine balance. Why would this not be a concern when installing the aluminum single mass unit? Anyone have any thoughts or experiene?
