basically if you car needs a hub ring it will require 74.1 to 72.56
is either that size or your wheel has to be hub centric. sometimes when you buy used wheels is good to drive their car with the wheels on as it can be a vibration that the prev. owner never fix. like a out of round wheel or bent wheel.
but i do wish you the best in hopes that the proper hub rings and road force balance will do the trick. ( by the way the road force balance will let you know if its a wheel deffect)
