WHY the hype on SPC Upper Control Arms? | Vehicle Alignments EXPLAINED!

CLARIFICATION: The positive and negative caster on the page refers to the upper control arm adjustment. This means that moving the upper control arm joint as close to the car and the lower control arm joint as far away from the car would provide the greatest caster from the body mount. By placing the upper and lower joints as far forward, this provides the greatest tire clearance with the least dramatic caster.

Alignment terminology I found to be pretty confusing at first and understanding the geometry to realize why certain control arms were advantageous was also complex. Check out the video, I try to unpack that a bit!
