Great thread. With some very interesting positive rubbing results. I would consider mine also quite surprising.

Fender Modifications: (F) None (R) None
Rubbing?: (F) No. (R) Yes, both sides, outside corner of tires rubbing the plastic nub on the wheel well liner mostly on bigger bumps at speeds over 40mph. Also over larger rounded speed bumps (not the small pointy ones). I have smoothed down the plastic significantly via my rubbing, and have also used a Dremel to smooth it further. I'm still rubbing, albeit not as much as immediately after the simultaneous suspension and spacer install.
