Here's what I can say along a tech write up so far:

This kit is the likely the cheapest possible way to go considering time/money. The brackets themselves are $100 (elsewhere up to $250 for the exact same thing) and to source the rotors, calipers, bits and pieces at a parts store new would be over $150.

IF you can find the rotors, calipers, hoses, hardware, etc at a junk yard for under $150 (which you can, if you can find the right donor) then you're golden. I have SO FAR not found the parts. The brake assemblies are often the first things to get stripped.
