The old way of lowering these cars was simply to invert the upright (shown inverted here). Since the upper and lower trunnion bushings have the same outside diameter, this can be done, but several serious problems then exist. First, the camber will be off to a considerable degree, which must be corrected by heating and bending the slender portion of the uprights. Then the outer tie rod end will have been moved to a position 2.5 inches higher than as it was originally, which creates enormous bumpsteer. That can be corrected by more heating and bending of the steering arm, returning the outer tie rod end to its original height, relative to the suspension pivot points. Fatman developed their new parts with both the drop and correct geometry included.
