You can pick up a set of calipers with pads out the door for just under $400 including shipping. The Baer rotors are about $150/piece, and I had the hats powder coated semi gloss black. I only did that because the rears only Wilwood kit are already black on the hat. Like I said you do not have to change the rotors.
You get a lot of people that bag on them and say the stock calipers are just as good if not better. Truth is, the stock brakes for these trucks were actually pretty good. But, like I said before with repeated stopping these just seem to keep performing, where my factory brakes did not have that same ability to avoid fading. And they weigh significantly less then the stock D52's
