I have the same setup and I am using these parts
http://www.wilwood.com/Rotors/RotorProd.aspx?itemno=160-0867http://www.wilwood.com/Calipers/CaliperProd.aspx?itemno=120-1360I am getting an adapter laser cut to adapt the rotor to the output flange and making a bracket that will use the rear housing bolts to hold the caliper.
That is a mechanical caliper so it will not bleed off and release over time but what I think Im going to do is put a heavy spring on it to keep it clamped down and have a small air cylinder connected to it with an air parking brake switch like on semi's. So when there is no air in it the brake is set and when I want to drive hit the button and the air releases the brake.
