The calipers are pretty expensive from satan. If I remember correctly they were over 150 bucks each. Your best bet is to find some on the dsm trader or in your local junkyard. I got mine from checker auto parts for 60 each. They came with some cheap brake pads, the caliper and the mounting bracket. The core charge is 50 bucks each so that can get kind of pricey if you don't have a core. But yeah, you find those calipers and thats all u need with the aem upgrade.
