was going to say the metal arch behind the plastic arch looks different? what the measurement from the wheel to the plastic arch? would need to be a proper big hit to knock the whole rear beam out to one side. the fact the wheels are straight and the car doesnt crab down the road would lead me to say the body had taken the hit and thats where the miss alignment is.Hmmm I may have answered my own question... looks like the O/S arch is a lot more crumpled than the N/S, probably the car had a coming together with another one on the race track, but you can't see it with the bodykit on..
