Update. I used a dial gauge and measured both inner and outer disc faces of both front disc's while installed. I measured several times each disc.
The right front disc has a run-out of 0.005" and the left front disc run-out is slightly over 0.004"
The directions with maximum run-out I have for APracing BBK disc's is 0.0003". See attached document.
I did not have a magnetic dial gauge such as in the instructions but used a standard one with vise-grip & adjustable extension which works fine for most disc brakes.
So, the tough question is, is 0.001" ~ 0.002" enough to cause the vibrations I'm getting? A tech rep at APracing says it's possible. If I get two new front rotors, I sure hope it fixes the issue.
