IS F (2008-2014) :: Inner Edge Of Tire Sidewall Worn?

I am lowered on KW V3's, running Figs lower control arm bushings with toe set to 0 for alignment just to be safe. Before upgrading to the Figs CAB's, I had the usual inner tire wear on both fronts. I then set the alignment to the safer toe=0 and it got better but still not perfect, so we installed the Figs bushings which made things great.

In the last 20k miles, something is off. My LF tire (Michelin Pilot Super Sport) easily lasted the 20K miles with very even wear. But I've gone through 2 RF tires, with the same outcome. After about 8-10K miles, the inner edge of the sidewall is so worn that the tire has physically separated. If you see the pic below, there is significant tire failure. Same issue, 2 tires on the same side.

Now, if this was happening on both sides, I would assume it's the normal ISF inner tire wear issue. But since we upgraded the CAB's, still have toe set to 0 and the LF is wearing perfectly, something else must be off. A check of all the main suspension points shows all bushings to be ok. The car has never been in a wreck and you can see the alignment specs below appear ok. Tire appears choppy, like a toe issue but the Figs bushing appears fine.
