CTS V rears are a little less than 140 a piece brand new. The brackets are 150 for the set(120 now since there is a sale going on) and they use 350Z or EVO 8/9 rotors in the kit. Some use the 13" Evo 10 rotor as well.
Good setup and if I didn't already have Wilwoods, the CTS-V/350Z brembo would have beeb my next choice!
P.S Don't buy the CTSV fronts. Not much in the way of rotor selection (read: they will end up using big HEAVY rotors if you get a bracket fabbed up!). Alos, since the front calipers were used on a 14" + rotor, the mounting ears are slightly different.
Not worth the headache
