Feel free to comment if you can help me decide which is the better way.

in short my 19s offset 38+ is rubbing under full load on the rear back side (left), I read everyone who has 40+ offset was fine. No problem at all. hence I am really 2mm from the sweet spot.

I dont want to change tires or wheels as I am pretty set on the brand and based on my own reasons. wheels dont come in narrower 19s nor does the tire have 255/30 (current 265/30)

I am stuck with these options

1. Fender roll - the problem is Lexus unlike other cars, dont have much to work with, as the fender is already quite thin. the risk of damaging or cracking the paint or causing rust down the road is what I have to consider.
2. Chamber adjustment - as someone suggested for me , getting SPC control arm for the rear and changing or adding negative cam to the rear side but depending on how much I need to adjust, risk with this is chewing thru my tires.
3. Modify wheel -I found a local shop that can machine down the center bore/ring and get it down 2mm so that I basically change the offset of the wheel to 40+ and it only cost about 50 per wheel to do this.

Now what does everyone think? option 3 is most cost effective, it will also depend on if the center bore/ring is thick enough for this operation as no wheels are alike. I like option 2 because negative camber is usually a good thing for improving handling anyways and gives me future option for wheel choices. I am less keen on option 1 for the risk of body panel damage where it may be irreversible.

The photos above are misleading as the point of failure is not from the backplate...and in reality we don't know what caused the failure, or the point of failure.
