No, it would be the other way around, you have more runout (close to 3x) on the driver front based on the above numbers unless you missed a 0.

I can believe those numbers. Runout itself does not cause pulsation issues with a floating caliper, DTV is what causes pulsation. Excessive runout will cause DTV over a short period of time.

You need to either machine the rotors on-car or replace the rotor and get runout down to a more reasonable level. .001" or less is what you should be aiming for.
