For now we are recommending that racers don't run the setscrews and allow the bumper to hold the hinge pin in. We have been running it like this with no problem. What's even more ironic is that we never saw this during any of our testing with the preproduction models and that I can tell you is frustrating for us. Even at the WC we never had any issues and that track was very hard on cars.
