I'm pretty sure your brand new rotors aren't out of round.
Also check wheel balance, in case.

3)break in the pads again. How was the car driven since you put the pads and rotors in? I rec light driving for at least 100k until you really step on it. You can attempt sanding down the pads and cross hatching the rotors using sandpaper. Did you clean the rotors surface before installation? There is a coating of oil put on the rotors to prevent it from rusting on the shelf.
You can do step two and three together. Make sure you lubricate the slider pins with slider pin grease (lordco has sylglyde)

didn't invest in a dial indcator because most people suggested it's overkill. If it's truly bad rotors then i'd get the mfg to replace them.
yes rotors were cleaned before mounting. yes slide pins were greased. I'm aware of akebono's recommended 400-500mi bedding process and I usually throttle/brake like a grandma anyways.
I think I ensured the rotor screws went into the correct holes but one wasn't completely flush because of the rust on the threads. Didn't think much of it because these screws are apparently optional.
wheels are directional and i just rotated them 6 mo ago. How do I check the wheel balance? As long as the weights look the same on both wheels?
when installing pads do you have it resting against the rotor surface or have a bit of gap and have it sit towards the outer edge of the caliper bracket? I didn't think it'd make a difference because once you brake the pads will just rest on the rotors?
