I just got off the phone with a BAER Rep. and he told me that the rotors for the rear are going to be $120 a piece for the 11.35" and $125 for the 12". I dunno what ones I have, but I seriously hope that they can be found at a cheaper price then that ! ! ! BTW they are 4 lug And I hope that I dont hve to buy new ones for the front and they can be cut.....
