Still think a check of install is in order to determine miss aligned pad.
Some track pads make a grinding noise when cold, but a check of surfaces for a rub is in order.
So re-checked the install and everything is nice and tight. I think the bracket might be a little off which is a QC issue for Wilwood.

Drove it some more and did some more hard braking. At low speeds below 30 MPH, I can slightly feel the rotor grooves in the brake pedal.

At higher speeds 75-60, when I lightly brake, the car shudders but as I apply more pressure, the car does not shudder anymore. I think it's because the pad is lightly getting caught in the slots in the rotors and causing this issue. Maybe more time with it, it will wear the slots some more.

Car still pulls to the right for some reason. Might be an issue with the caliper not having equal pressure on all 4 corners.
