I started with the SPC arms in the C position and that rubbed badly, as you can see. After more tinkering, I set it all the way back at G as recommended in the SPC alignment thread :
SPC UCA Alignment Sheets
and set my lower cam bolts to max caster to offset. Took it to Firestone for alignment and it drove great.
Maybe later I'll get
those nice lower arms which move the ball joint forward 1" for more caster...
