Im thinking of swapping my wheels for some vertini drifts 20×8.5 fronts and 20x10 rears but they are coming off a fg onto a bf, just wondering will I have trouble fitting them depending on offset? I have normal size brakes but I have heard with a certain offset from the fg they hit the control arm? Unaware of the offset at the moment will post when I find out. Thanks in advance!
