John, The point is that the unit you suggested can not be used. Rotor, hub, etc. You can't get the weight savings you espoused in your email. The difference between a cast iron VW rotor and that steel rotor, I would imagine, would be significant. Can't tell, don't have those two units in front of me.

And the difference in weight between cast iron and steel? Not much, and you know, I haven't spent more than 5 minutes researching it .. how much time did you guys spend and how in the world can anyone think that replacing those large cast steel drums with discs and aluminum hubs will weigh more???????????????????? Have you ever even picked up a backing plate for these cars? Very heavy. Art wrote: >John, > >That setup uses steel rotors.
