I bent my rear passenger lower control arm a couple weeks ago, replaced it with a new stock arm, and now my rear thrust angle is at -0.30 degrees. A week before I bent the CA, the rear thrust angle was at -0.06 degrees. Nothing else looks bent in the rear. It does kind of drift to the right, but not sure yet if that's because of the crowned roads.

1) Is -0.30 degrees enough to be worried about?

2) What would I need to be able to adjust the rear thrust angle? An adjustable pan hard bar or adjustable upper/lower control arms?

Here are the alignment settings(new CA / old CA)
CAMBER LEFT: -0.1 / -0.3
CAMBER RIGHT: -0.4 / -0.2
TOE LEFT: -0.32 / -0.05
TOE RIGHT: 0.27 / 0.07
CROSS CAMBER: 0.2 / -0.1
TOTAL TOE: 0.05 / 0.02
THRUST ANGLE: -0.30 / -0.06

Thanks
