I'm not sure if this has been covered before. Search didn't bring much up. My OEM stock pads and rotors are pretty much shot at 70K miles and it is to a point where I think my overall stopping power is significantly less than it should be. That being said, I am set on getting this setup, but from the epic thread about the install, it looks like some parts from the Camaro can be used in place of the CTS-V OEs. Please correct me if I'm wrong here, but the Camaro rotors are the same size as the CTS-V rotors and the 2004-2007 CTS-V rear calipers are identical to the 2009 rears. Is it not a lot cheaper to use Camaro parts in place of the CTS-V's or am I off my nut here?
