Does anyone know if the first generation and second generation ceramic rotors are the same thickness?

I installed what are probably second generation calipers and brakepads (the ones from the current PCCB kit that Porsche sells) and first generation ceramic rotors. Even after bleeding the brake lines a second time, the brake pedal travel is 1 and 1/2 to 2" greater than with the steel rotor braking system. Braking is not as good as with steel, but may improve as the new pads wear-in.

On the side of the rotors (along the SS hats) are the min. tolerance figures. You can read those through most wheels without pulling them.
