I need new rotors and calipers all around in the rear. For some reason my car came equiped with awd calipers in the rear, I dont know about the rotor, except the caliper only uses about half the thickness of the rotor. I know fwd calipers are bigger in the rear. Satan was trying to tell me that the rotor is 15" that cant be cause my car came with 14" wheels. So is there any company that sells a package with rotors and calipers for 300-400. And is a bigger caliper better than a bigger rotor. Satan claims that fwd has a 14" rotor but larger caliper and awd has 15" rotor but smaller caliper. Or can I use fwd calipers on awd rotors. I know rre claims they are the same rotor but I order aftermarket and brought them back because the caliper did fit. I dont know about the big brake kits so any help is appreciated.
