any reason why you went with the same size caliper in the back instead of running the Gen 3 rear viper calipers, which are also a 4-piston design that looks like the fronts, but with smaller pistons.
I put gen 2 front brakes on all 4 corners on my Dakota, with 13" rotors (same bolt pattern as Viper) but I have factory RWAL that keeps me from locking up the rears. --and it works great despite the RWAL being designed for a disc/drum system.
