Looks like there's an "offset" issue with the passenger side rotor. The issue can be caused by a missing part or mismatching rotor hat to the driver side or somehow the wheel bearing goes deeper onto the spindle more on one side than the other side. The latter is the least plausible of the three but not impossible. Any one of the above will cause the rotor to be not offset correctly relative to centering the rotor to the caliper and the ball joint. The rotor looks like an aftermarket two-piece rotor with aluminum hat. The rotor friction ring may be of Coleman brand. With what little I can of the caliper it does look like a 993 Carrera(not turbo) caliper by the radial-mounting pads.
If I were you, I'd measure the driver side rotor hat and measure how the rotor is center to the caliper on the driver side and compare to the passenger side. A caliper adapter bracket is necessary for this brake conversion so measure the bracket to see if it matches the other side just to thorough(the bracket is responsible of offset of the caliper to the rotor, but not for the rotor to the ball joint). If it happen to be missing item #24 in the image then it will change the offset in an unfavorable way and more disturbingly render the inner(bigger) bearing to be not so effective, which I guess that's probably why the factory engineers designed this arrangement with a smaller outter bearing as a back up plan.
Good luck.
