The 1st part is due to changing the SAI.The front cam bolt is mainly camber and the rear cam bolt is mainly caster.God knows what your caster is,might have negitive caster now.
Actually, by turning both cam bolts the same amount, it moved the lower control arm outboard evenly and cancelled the excessive positive camber. The SAI is now closer to stock. The wheel spacers increased the scrub radius which has helped the handling a bunch.
