They're big, cheap, and American.
Having said that I have been tempted to try them - they make 11ty-billion different types of calipers!
As long as the design is OK(ie are stiff enough across the bridge, take a large diameter rotor / thick rotor etc), they should work fine...
Give it a shot and let us know how you go!
If you need some radial mounts machined I might be able to put you on to someone
