on the rear right i have to put a spacer inbetween my wheel and the brake drum otherwise the wheel scrapes against the susension arm but it doesnt do it on the otherside. why is this, because if i take them of the is no noticable bend in the arm.

There is a lip on the side that scrapes that catches on the inside of the alloy sometimes and its slightly different on the other side. The lip that sometimes catches is on the rear arm, but it catches further up anyway
