Anyone else experience the rear inners of their tires literally gone after installing their ES bushing kit back there?
I am assuming my guy did not align the rear properly or something, but 4 tires only have 5K on them and they inside of the rears are gone.

Will toe off have the same effect? I noticed that the rear is extremely dancy, but I never looked at it until now.

toe will cause the wheels to wear quicker than camber will

yes toe will cause a similar wear pattern, but not exactly the same, did you have the car re-aligned after the install of the bushings? if you did he definatly didn't set the car up correctly, i have all the es bushings in my car and no abnormal signs of wear. get a 4 wheel alignment from a reputable shop, don't go to town fair tire or pep boys or places like that, they will just set the toe and let you go, if i had to guess your problem in the rear is probably from the toe setting anyway. request a print out of the alignment specs from the shop, if they won't do it there is a reason, get the before and after specs
