I think it could be done cheaper, but requiring more work than picking up a phone. I ordered the brackets for $80 from MAF, rotors were $26 each, local shop to bore them out around $20, raybestos hose $13 each, set of loaded calipers is $82, proportioning valve another $40 from summit. $300 ish for everything needed, add up their list of costs for the same stuff, and you will see a nice difference. Look on the technical links page and you will see tons of different write ups of rear brakes. I just picked my favorite and copied it.
