No they're not. The fronts are 14" diameter, the rears are 14.4".
If you look at the rotors themselves, there is less actual swept area on rotor by the caliper. Brake bias is tuned in the hydraulics anyways.
Anyhow, I'm pretty sure the rear rotor is larger to incorporate the parking brake assembly, which I believe on the CTS-V (the Camaro looks to be getting that setup) was inside the rotor hat. I can assure you it has nothing to do with tire width. Don't believe me? Look at the C6Z.
