I been running 2 gold washers under each Bellcranks since very beginning, to adjust the bump steer on the fly with following amount of washers under each ball stud of the steering hub.
- Low roll center: 2 washers
- Med roll center(low block with a 1 gold washer): 1 washer
- High roll center: no washer.
in my measurement on a hudy set up board with total of 4deg Castor, the machine is in neutral bump steer (0") with those set up.
the image showing Low roll center set up as I ran last week.
add: this mod also eliminated rubbing against upperdeck from ball end on the servo saver.
