and/or maybe they popped his lca bushing back into place for the second test.

 

To note on the alignment sheet - they did adjust with the front caster to help compensate for the right drift. I have the SPL V3 upper control arms. That may or may not account for the setback change.

Thanks for the feedback guys. I am going to try a different set of wheels and tires soon, report back, and go from there.

 

I think root cause has been identified.. car actually drifted left on a road slanted to the left, with about the same intensity as the right drift. It did still drift to the right on a road slanted right - this all with someone else's wheels/tires.

On the same road with my wheels/tires the car wanted to go straight. The difference was pretty obvious to me.. strange, but, obvious. Time to wear these tires out.

 

Old worn tires will follow the road surface if it's uneven.
