ive got a 2013 dodge challenger rt.got it brand new,never any suspension mods.i did add aftermarket wheels with the exact same backspacing and size as the originals.18's.all was good until i got to about 95,000 miles then it started eating tires mostly on the rear but the front also.rear is visibly leaning in. alignment shop says its roughly 2 degrees out on both sides on the rear.visibly looking at it i cant see anything obvious.when i say it eats tires i mean the inner edge will hit metal in 1500 miles on the rears.any help or ideas appreciated...
