C6 rear rotor weights

[ghoffman]

I had an interestiing finding. I decided to try the 13.0 inch C6 Z51 rear rotors on my C6ZO6 because they are a little smaller (so I assumed lighter, NOT!). I have the Wilwood SL-4R calipers on the rear so it is simply a matter of removing some small washers to change diameters. The C6ZO6 rotors are larger at 13.3 inches diameter, versus the 13.0 for the C6, but are lighter than the smaller C6 rotors! The 13 inch C6 rotor weighs 20.0 pounds, and is directional and left side only. The C6ZO6 rotor is 19.2 pounds and is 13.3 inch diameter and is not directional (it looks like a "Kangaroo paw"). Oh well, I guess I have spares now...
