Quick update... I finished up the mods aft of the front wheels. I ended up turning the "U" shaped bracket into an "L" shape such that the mounting hole was now ~1/2 inch or so further back. Then I drilled a new hole in the liner and bolted it down with the factory bolt. I thought I had taken pics but apparently I failed there.
Got it aligned at an off road shop (Round2 off road in Cedar Park) after Lexus said they couldn't handle the wheels/tires for an alignment and wanted a million dollars to move TPMS sensors.
It drives beautifully now, tracks well. I was a little worried after I installed the tires prior to the alignment because it was a bit squirrely and not great but the alignment got everything driving nicely.
There is def more noise. Sometimes just a bit more, sometimes an annoying amount, depending on specific road surface.
Even the wife, who generally was skeptical of why it needed new wheels and bigger tires, is snapping pics and sending them to me, like "hey, it rained, look how good it looks all covered in rain drops". Ha.
Now time to go learn how to drive this thing on trails.
