Hmmm, well, all i can assume is the car has had a knock, because the arm itself has a very very very slight curve on it, but you can see the where it steps down to go through the TCA it counter bends in the opposite direction, and the joint on the mounting plate also looks to have a very slight bend on it. I presume the whole arm spins round when adjusting the castor angles/length, so this will make the adjustment a nightmare, no doubt it will go on and not be noticeable but i know its not right and theres nothing worse than having to fight with things.
