Goody...pad knock-back is from loose wheel bearings...sometimes you guys should listen to those of us like me who ran those same brakes on the road course at 130+ mph with lots of track mileage/time. The orig way to set up wheel bearings in not for going 130 mph. OK??? More than 1 car with the same set up btw.

The proper modern adjustment procedure is

While spinning rotor CW tighten wheel bearing nut to 20 fl lbs.
Loosen nut
While spinning rotor CW tighten wheel bearing nut to 90 to 120 INCH pounds with a BEAM torque wrench.

I am not here to argue. I know what works so why don't you humor me and try it? If you have pad knock-back after that you have something else wrong and/or the torque setting needs to be a bit more. I never ran small outer wheel bearings.

As far the Op and his size matters...minimal difference in the size...ducted air on the brakes matters, for the street with no track time the 11.75 is more than adequate. Choose the correct brake material.
