Yes, the tabs should be relocated. Any time the rear fenders are rolled you should just relocate the tab at the same time as it makes the most sense. Externally it doesn't hurt anything and it makes one hell of a difference in rubbing.

i have 17x9 +45 with a very mild roll and the fender tab relocation. it will come down to your alignment and how low you are on any rubbing issues. this is where i stand.
