I stand corrected.
$1600 isn't a bad price for as complete as the kit is. Calipers are two piston units which means they are either vette or mustang units. 13" rotors will require 17" wheels. No reason to think they are bad setup and they would be comparable to any other late model 13" brake kit you. Two piston calipers will provide more feel than the stock single piston type. Aluminum calipers will save a few pounds of weight.
For comparison, the ARE 13" Viper kit is $995 for the hub, rotors, and brackets less the calipers. Used calipers are $300-500 a pair, so throw in hoses and your at or above the same price.
