Wilwood Disc Brake Issue

I have been using the 73 disc setup from Dr Diff for a year or so. Biggest issue I've had is the passenger caliper seems to not fully release and the discs drag.

While troubleshooting a front end noise, I went ahead and replaced the front brakes with Wilwood discs & kept the MC as it was. Had no problems with the installation but those brakes don't have near the stopping power of the Dr Diff units. As always with brakes, I cleaned the rotors before putting the discs into the caliper and made sure there was no contaminants on the pads. When I apply the brakes they act like they are wet and not grabbing the rotor very well. No leaks out of the calipers or anywhere else so not sure what's going on.

Kinda at a loss here.
