Ok, lubed the snot outta everything. Stretched the v springs a little more. Found a loose clip and fixed that (hopefully that was the problem). Going on a drive this evening to see if its fixed.

Have you performed a pad bedding procedure? If you have, maybe do a couple more, with a cool down period in between.
Since everything is new, consider swapping left front and right front pads and bedding them again.
Are you sure it's the front brakes? Just spit-balling.

I just hit both front rotors with my IR gun . They are within a degree of each other. I don’t think they are hanging up. I have absolutely no idea. Maybe new pads?

I seem to recall the Hawk pad bedding procedure was different in the past.
Current:
1. To break in the new components, make 6 to 10 stops from approximately 30 to 35 MPH applying moderate pressure.
2. Make an additional 2 to 3 hard stops from approximately 40 to 45 MPH.
3. DO NOT DRAG BRAKES!
4. Allow 15 minutes for brake system to cool down.
5. Your brakes are now ready for use and can be driven normally.
That's a lot of stops. IIRC the old advice was moderately aggressive braking 3 or 5 times from 60ish to 20ish to get them hot, but never come to a stop. Stopping allows transfer of pad material to the rotor and is to be strongly avoided. After getting them hot just keep driving for 10 minutes to cool them off before coming to a stop.
Anybody else recall that?
