Sway Bar Question

I've got my Calipers on the rear for 2 B/Cudas & they both handle & stop like a dream. I've read over the years about not wanting the Calipers on the rear (I never really heard a good reason for this). I haven't seen this, or any other problem by mounting on the rear. Because of this, I don't have any trouble with Anti-Sway bar interference (w/ 205/50r15 tires). Hopefully, no one shows me that I've erred...
