http://www.crowbuilt.com built me a set of one-off brackets which allowed for mounting some Strange Engineering floating calipers on my spindle mount front wheels (which are designed for bolting on V8 style rotors - I went with Strange parts there too).
There wasn't a lot of room and the caliper bracket was built specifically for the parts combo that I have (wheels, spindles, calipers, and rotors).
Here are some pics of my setup:



The following thread is an old on from the CLF, and it contains some addt'l pics of other spindle mount setups that I gathered when researching mine:
