No longer true (see my post above). I bought 2 rotors and don't even have K-H brakes. I gave up on the full K-H setup since people ask outrageous prices for used, rusty parts, plus rebuilt calipers are $$$$ and who needs heavy iron. I have a long-range plan to mount the rotors on my drum hubs. I got Wilwood calipers off e-bay. I need a plate to mount the calipers and an adapter for the rotors. I think it will fit under my 14" wheels. If I only had CNC mill or lathe, but that is next.
