UMI adjustable upper control arm adjustment?

[ham1974]

What is the standard procedure for adjusting the upper arms? I assume making them the same length as the stock arms is a good starting point? What are the benefits to adjusting the uppers?

 

[melloelky]

are you talking about upper rears or fronts?

 

[ham1974]

Rear arms.

The adjustment is to set the pinion angle.

What is the idea angle? 3 or 4 dig up or down?
