I've busted the right steering arm & door mount twice, and the left ones once. Both were from running into people. You'd think people would be softer or something. I've been lucky and CA glue has held everything back together both times, although I don't jump it anymore. But I decided to make myself a bumper out of galvanized steel to take some of the shock away from front-end collisions. I bolted it to the same holes as the stock front bumper, using small bolts that should act like shear pins.
Fortunately, I've not yet tested it in a real world situation
