hey all- alright so my subframe is a little bent froma drifting accident

, there is a little toe in and positive camber on the right rear after alignment. so i was thinking, would it be unsafe to run adjustable RUCA's and rear toe rods on a bent subframe?
the car actually handles quite well still for some reason, just feels a little wierd. the shop i took it to never even discussed pulling the frame, just finding a used one and putting that in, would pulling the frame make it really weak or anything negative? im just tryin to find out all my options of fixing it.. thanks for your help! oh and one more thing- what controls toe in the front? tie rods?
