Used calipers/brackets with no pads on ebay are 199+ shipping. Same with the fronts. So your looking at 430 bucks for used calipers.
Im looking at the pictures, and they said under 50 miles of use....the corvette lettering in pretty beat up for being under 50 miles.
Ill sell you mine for 350 and I can meet up with ya, since your only about idk hour/hour ana half away. Ive got the stock rubber lines, and hawk pads with mine still.
