my asr arms had the same exact problem as i also used shee spindles except my arms use hein joints instead of ball joints for me to ge a zero reading i had to have the heims screwed to far out . ideally u want 3/4 of the threaded area on a heim joint or threaded ball joint for that matter screwed into the arm. mine were only in a lil less than 1/2 the threaded area so i had asr make me a new set of upper arms that were 1/2 inch longer
