Kelly,
    The aluminum one I'm getting is 10.7 lbs but that i= s before removing the replaceable iron friction surface.   Probably ab= out 3 lbs for the iron piece but just guessing.  I don't plan on remov= ing much, if any, aluminum.   There is a LOT of in in the center area.=

I'm thinking we are over reacting on the strength issue.   The Ro= ss drive used a custom aluminum flywheel that was just a plain 5/16"  = or 3/8" thick aluminum disk with steel ring gear.  Never heard of a pr= oblem with that part.

Subject:= [FlyRotary] Flywheel thickness ?

Question for David, Kelly o= r anyone else playing with lightweight flywheels.  I have one on the way but won't see it u= ntil I get back home in October.  I'm working on a new design to repla= ce the stock flex plate and need to know the thickness of the lightweight f= lywheel.  Every picture I see of them appears to show an almost flat d= isk which would imply that there is MORE room between it and the redrive  adapter= plate than there is for the flex plate which has about a 1 1/4" dish in it= .  BUT,  much of the discussion seems to imply that if anything, = there is LESS. 

Anyone able to tell me the actual thickness of= these aftermarket lightweight flywheels?

I'm looking at the aluminu= m versions for weight reasons and also because the iron friction surface is= removable ( for even less weight).
