Front Pivot Points

Bob, if you can give me any insight here it will be appreciated. Specifically - if we pull the alignment shims and mount straight to the upright, will we affect the timing such that it could not be adjusted in the arms provided the arms have enough adjustment? It is the location of the upper pivot with respect to the lower I am concerned about.

A little change won't effect things adversely.

The SPC cross shafts are not offset so we will have moved the pivot point inboard by the amount of the original cross shaft offset + the thickness of the alignment shims. I just don't quite have my mind around this yet.

If the proper timing cannot be achieved, we will either run nominal block spacers behind the cross shaft or use the original Moog cross shafts or a combination of both and then fine tune with the arms.

The stock ERA arms offset the ball joint 0.9" to the front (from midpoint of the inner mounting holes).
