To put this to bed.....The front GiroDisk 340mm rotor weight 1.15 lb less per rotor than a new stock 318mm rotor. The rear 325mm GiroDisk rotor weighs 1.5 lb more than a somewhat worn stock 299mm rotor. GR front=18.09 GR rear 15.5 stock front=19.24 stock rear=14 you might wonder why. I think (by looking) the rear GD iron part has greater metal to air ratio than the front GD. also (325/299)^2 is greater than (340/318)^2

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

That's awesome and thanks for that.
Yes not much in weight savings But big difference in size and stopping power and pedal feel I’m impressed with my set up
