I looked at some hydrolic Quartermidget calipers yesterday, i'm gonna work with those and see what i can come up with for a mechanical version. Here are my pics of a mount and your style wilwood caliper. Its not 100% right because i do not have the spot caliper to work demensions off of, but its an idea. Plus my rotors aren't as deap as a 911's, so i have more room to play with offsets.
