The good calipers (and their matching fork mounts) unfortunately only work with newer, thinner, lighter 5-bolt rotors which, also unfortunately, only come on ugly Comstar rims or, on some CB750ks and CB650s, as a single disc spoked wheel.
I have never seen a dual-disc, spoked wheel that works with the 5mm thick late model rotors and matching calipers. Oh, and most of them are 19" so you will have to search before finding an 18" wheel to match your stocker. This applies to the above too.
The best calipers for the above swap are the ones on 1980 CB750fs because they are dual-piston and will still clear spokes.
Here's a fun, geeky experiment not entirely proven to work: FZ750 floater discs have the same bolt pattern as a late 70s CB750k spoke hub. Dual floating discs on an 18" spoke wheel = modern sweetness. The unresolved issue is the caliper mounts/which calipers to use....probably WAYYY too much brake in the end, anyway.
Honda go sideways!
