Looks to me from the pic that they are bolted on the wrong side. The factory arms can be reversed. Why not these? I've made the mistake before myself. It's easy to do if you are assembling from a pile of parts.
Nope, bolted on the right way. The kink in the arm tells the story. They are bent. It was in and working for a few miles, stop the car after a burnout and back it up to launch it, when I launched it the car jumped to the side and would go anywhere but straight.
