Does anyone know the differences between the RKSport flywheel and the Fidanza flywheel? Weight? Anything?

Received this reply from Jeremy @ Spec:
"There are a number of differences in these units.  They use different plates, discs, and bearings and also have unlike geometry’s.  The SC89 series clutches are for Ecotec motors while the SC62 are for use with the earlier non-ecotec motors.  I hope this info helps.  Let me know if you have any further questions.  Thanks"
 
 
so I guess it should be "Vin 4" not "Vin F"?  and 00-02, not 02-04

On their web page, it lists the SC62 as a 'VIN F'...... but the email says "non-ecotec motors".......   So I take "non-ecotec motors" as meaning 2200 OHV, aka VIN 4.
