Is there a downside to adjusting the upper control arm shafts so that the upper ball joint is more towards the rear of the car? I have rollerized upper control arms and the ability to offset the shaft. The last time I had the car aligned the tech was not able to add additional shims to the upper control arm because the bolts were not long enough. To compensate he used the adjustable strut rod to pull the lower control arm forward. I guess this was ok but one positive caster was low, and two the front tire was closer to the front fender. Should I just install longer upper control arm bolts, offset the upper control arm shafts or both.
