They have been selling take off GT500 6 piston fronts with calipers, rotors, lines, shields and pads for the $800ish range for a while. You see a few people trying to flip them on the forums for like $1200 - $1500 from time to time but this is where they probably get them from. ShelbyAuctions also sells Baer and Willwoods at good prices too every now and then. They don't have anything listed right now but all I did was add them to my watched sellers list and check every couple days sorted by "time newly listed" and then watched the brake ads. I bought the first set I bid on for $756 shipped, arrived in nearly new condition. When they post them they usually post about 3 or 4 sets but with the GT500 run being over they may have run out from converting to Super Snakes. They are still a good place to get take-off parts from though such as wheels and superchargers.
