Spec B Rear Control Arm

Damaged my rear end in a curb collision - shop said my rear upper control arm was damaged. It was bent but they straightened it. Should i replace the part?

I have to get my rims replaced because im not riding straight or without vibration but as far as i can tell the camber is fine with the straightened bar. Not sure if the shop just patched me up and passed me along...

Since im down there i was thinking of replacing my both OEM control arms with Spec B. control arms both upper and lower and doing some sway bar work with new endlinks.

Is the upgrade to Spec B worth it? My bigger concern, after reading more is how the bars will react and/or damage the rest of the suspension with Chicago potholes and f#$#@'ed up roads.
