I've often wondered if mounting the caliper in front of the spindle vs behind affects the design "dive" characteristics of the suspension under hard braking situations. I don't know the answer, just asking for other opinions.
The suspension will work the same.
Just for grins, I have wondered if moving the calipers to the rear could even affect the Fr/Rr center of gravity? Yeah, it is probably so small of a change it isn't worth mentioning.
